Elmira Stove Works 1956 - Manual (Page 6)

NOTE: If a gas burner burns with an uneven orange
flame, reposition the burner cap so it sits flat on the
burner housing. If burner lights slowly, have your gas
service person check the gas pressure to the appliance.
If a top burner flame has been adjusted too low, the
electronic ignitor may start to spark. Readjust flame until
ignitor stops sparking.
When cleaning around the surface burner, use care. If
cleaning cloth should catch the ignitor, it could damage it,
preventing ignition.
If surface burner does not light, check if ignitor is broken,
soiled or wet. If clogged, clean the small port beneath the
ignitor using a straight pin.
Wipe acid or sugar spills as soon as the cooktop has cooled
as these spills will discolor the porcelain.
See Cleaning Guide – Page 28.
OVEN VENTING
- GAS TOP MODELS
The Oven Vent
Hot air and moisture
escape from the oven
through a vent in the
center rear of the
cooktop. Do not
block the vent.
Poor
baking/roasting and
bad combustion can
result.
The oven bottom must be in place for burner to bake
properly on model 1956.
GAS SUPPLY SYSTEM
Gas and Electrical Supplies
Before connecting to the supply systems, be sure that the
installation conforms with the local codes or, in the
absence of local codes, with the National Fuel Code, ANSI
Z223.1 latest edition or in Canada, CAN/CGA B149
installation codes. See page 4 for electrical requirements.
Gas Piping to Range
The gas supply piping to the range should be 3/4" pipe
which is then reduced to 1/2" at the regulator. With “LP”
gas, the size of the piping to the range should be
determined by your gas fitter.
When connecting pipe to the die cast regulator fitting, use
two wrenches. Excess pressure or tightening the pipe too
tight can cause the regulator to crack, resulting in a gas
leak or a possible fire or explosion.
Make sure that if flexible connectors are used in
connecting the appliance to the gas supply, they are AGA
and/or CGA approved. Poorly designed connectors can be
a source of gas leaks. Even if AGA/CGA approved
flexible connectors are used, the customer should be
cautioned against kinking or damaging the connection
when moving or cleaning the range. This could cause a
gas leak.
Manual Shutoff
Install a manual shutoff valve in the gas line, in an
accessible location, near the unit. Know where the gas
valve is so you can shut off the gas to the range quickly.
Suitable pipe thread sealant must be used which is
approved for use with “LP”/Natural gas. Be sure to use
this thread sealant on all pipe connections.
Pressure Testing
The appliance, and its individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/3 psig (3.5kPa).
The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve
during any pressure testing of the gas supply system at test
pressures equal to or less than 1/2 psig (3.5kPa).
The gas supply pressure for checking the regulator setting
shall be at least one inch w.c. above manufacturer’s
specified manifold pressure.
Gas Leak Testing
After the final gas connection has been made, all the top
burner valves should be closed and the gas supply and
manual shutoff turned on. All connections in the gas
supply line and in the range should be tested with soap
suds or electronic sniffer for leaks. If a leak is present,
bubbles will appear. The leak should be stopped by
tightening the joint, or unscrewing completely and
applying additional pipe dope and re-tightened. Any
factory connections which may have been disturbed
should be retested.
A match should never be used when testing for leaks.
All fittings have been tightened and tested at the
factory. If a leak is detected, tighten the fitting. Don’t
use pipe dope on factory fittings.

Top Burners
Your gas range is equipped with “state of the art” “Sealed
Gas Burners” and an “Auto-Reignition System”. The
sealed gas burners spread the heat evenly across the
bottom of the cooking utensil and provide infinite heat
control. The auto-reignition system senses when a burner
flame has gone out and will automatically reignite that
burner. There are no standing pilots to light or adjust.
See this page for cleaning and maintenance of top burners.
Operating Range During a Power Failure
To light a top burner during a power failure, hold a lit
match to the desired burner head. Turn the corresponding
control knob to any numbered position. After burner
lights, adjust flame to desired setting.
The gas oven requires electricity to operate.
Removal of Burner Knobs
Apply a piece of duct tape to the surface of the knob for
better grip. Pull off by hand or with a pair of pliers.
Manual Burner Adjustment On Low
The burners have been pre-adjusted at the factory for best
performance. You may manually adjust the low settings up
or down by removing the control knob while the burner is
lit and in the low position. While holding the valve stem
so it doesn’t turn, insert a small flat blade screwdriver into
the stem and turn the small brass screw slightly in either
direction until desired flame height is obtained. Valve
must be adjusted so low flame licks around burner cap no
less than 1/8". See figure 11.
Figure 11 Figure 12
NOTE: Low adjustment will not effect flame heights at
other settings. If a top burner flame has been adjusted too
low, the electronic ignitor may start to spark while burner
is on. Readjust flame until ignitor stops sparking.
Flame Appearance
The burners have been pre-adjusted at the factory to a
clean blue flame. On LP gas, a slight orange tip may be
visible. If flame is not as above, your gas serviceman can
check the regulator for proper setting with a water
manometer (U-gauge). The stove pressure should be
within + or - 10% of the pressure setting shown in this
manual.
GAS BURNER CLEANING
• The burner caps should be routinely removed and
cleaned. Always clean burner caps after a spillover.
Keeping the burner caps clean aids in proper ignition and
an even flame. Set burner caps into indents in burner base.
• For proper flow of gas and ignition of the burner, DO
NOT ALLOW SPILLS, FOOD, CLEANING AGENTS
OR ANY OTHER MATERIAL TO ENTER THE GAS
ORIFICE OPENING.
• Gas must flow freely through the small hole in the brass
orifice for the burner to light properly. This area must be
free of any soil and be kept protected from boilovers or
spillovers. ALWAYS keep the burner caps in place
whenever a surface burner is in use.
Occasionally check the burner flames for proper size and
shape as shown. A good flame is blue in color. If flames lift
off ports they are yellow and usually noisy. You may need
to clean the burners. See figure 12.
To Clean Burners:
1. Lift the burner cap straight up from the burner base.
2. Clean burner cap with warm, soapy water and a sponge.
You can also clean with a nonabrasive scrubbing pad or
cleanser. Do not clean burner cap in dishwasher.
3. If the gas orifice opening has become soiled or clogged,
use a cotton swab or a soft cloth to clean the area.
4. If ports are clogged, clean with a straight pin. Do not
enlarge or distort port. Do not leave anything stuck in
the ports.
5. After cleaning the orifice opening and ports, replace the
burner cap. Make sure cap is set straight on burner and
that the tabs on cap fit into the grooves of burner base.
6. Check the burner for proper lighting after cleaning.
7. Replace the burner cap, making sure the alignment pins
on the cap are properly aligned with the burner base.
8. Turn on the burner. If the burner does not light, check
cap alignment. If the burner still does not light, do not
service the sealed burner yourself. Contact a trained
repair specialist.
