This is a vented appliance and must be connected to a
chimney in accordance with the current installation
codes. In absence of local codes, install to the current
National Fuel Gas Code, ANSI Z223.1, or the current
CAN/CGA B149, Installation Codes. This model can be
common-vented.
A minimum four inch diameter (4"ø) B-vent or class A vent
is required. A minimum 10' vent height is required. Secure
the B-vent to the exhaust collar on the stove top with 3
screws. In cold climates, the use of a B-vent and an insu-
lated chase is recommended.
This thermally activated switch, located in front of the draft
hood, senses an increase in temperature and acts as a
safety shut-off (See 'A' below). It shuts down the gas to the
main burner in the event of a severe downdraft of air or a
blocked or disconnected chimney flue. If the flue is blocked
or has no "draw", the safety switch will automatically shut
off the supply of gas to the main burner within 10 minutes.
This switch must be manually reset by depressing the
plunger. Refer to Figure 2.
Tampering with the safety switch can result in carbon
monoxide poisoning and possible death.
This thermally activated switch, located in front of the draft
hood, senses an increase in temperature and acts as a
safety shut-off (See 'A' below). It shuts down the gas to the
main burner in the unlikely event of the unit overheating.
The HI Limit switch will automatically reset after the unit
has cooled down, resuming gas flow to the main burner.
A test for correct venting action must be made before
the installed unit can be left with the customer.
Follow the procedure below:
1. Close all doors and windows in the room / start
exhaust fans in the home / turn the fireplace blower off (if so
equipped).
2. Set controls to "high" and light the unit.
3. Wait 5 minutes. Light a match and hold to the front of
the draft draft hood. FIGURES 4 & 5.
FIGURE 4
Venting action is satisfactory, if smoke and flames are
drawn into the draft hood.
Venting action is unsatisfactory, if the smoke spills back, and
the flame splays outward. If venting action is unsatisfactory,
turn off the unit, wait 10 minutes and try again. If the smoke is
still not drawn into the draft hood, turn the unit off and check for
vent blockage or restriction. If necessary, consult with a quali-
fied inspector.
The Safety or Hi Limit switches must not be adjusted
or disabled.
In the event that either switch or any associated parts
are exchanged, only original manufacturer's parts
may be used.
