LEAK TESTING
WARNING! Before lighting your outdoor gas fireplace
be sure to read this section carefully.
Turn gas valve knob to the OFF position. Inspect the gas supply
piping or hose prior to turning the gas ON. If there is evidence of
cuts, wear, or abrasion, it must be replaced prior to use. The
replacement pressure regulators and hose assembly must be the
type specified by the manufacturer. Do not use the outdoor gas
fireplace if the odor of gas is present.
For LP gas, the pressure regulator and hose assembly supplied
with the unit must be used. Install the regulator into the 20 lb.
propane cylinder and check the hose and regulator connections
for leakage with a soap and water solution before operating your
outdoor gas fireplace. Be sure there is gas in the 20 lb. propane
cylinder.
1. Before lighting your outdoor gas fireplace, check all
connections for leaks using a mild soapy water solution.
DO NOT use matches, lighters or flame to check for leaks,
— you could cause an explosion. With the outdoor gas
fireplace burner control turned OFF, slowly open the
cylinder valve by turning the handwheel counterclockwise
(right to left). Apply mild soapy water to the connection. If
bubbles appear, a leak is indicated. Do not put the product
in service! Immediately close the cylinder valve handwheel
for propane gas or the manual shutoff valve for natural gas. A
qualified service person must be contacted to make the
needed repairs.
2. DO NOT SMOKE WHILE LEAK TESTING!
3. For LP gas (propane) models, leak test with a full propane
cylinder.
4. For systems other than self-contained LP gas (propane)
systems:
A. The outdoor gas fireplace and its individual shut-off
valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test
pressures in excess of 1/2 psig (3.5kPa).
B. The outdoor gas fireplace must be isolated from the gas
supply piping system by closing its own manual shut off
valve during any pressure testing of the gas supply piping
system at pressures equal to or less than 1/2 psig (3.5kPa).
5. After the installation of all gas-related items: i.e. hose, regulator,
LP gas cylinder, natural gas hose or natural gas regulator; the
outdoor gas fireplace control valve should be turned OFF and
the gas turned ON. This is known as "charging the system."
All gas connections must be checked with a soapy solution
while the whole system is under pressure.
To make a soap solution, mix together an equal amount of
liquid detergent and water.
6. Apply soap mixture to all gas connections. Soap bubbles will
appear if there is a leak. Tighten connections to make a proper
seal.
If you cannot stop a gas leak turn off the gas supply and call
your local gas utility, or the dealer from whom the outdoor
gas fireplace was purchased.
Only those parts recommended by the manufacturer should
be used on the outdoor gas fireplace. Substitutions will
void the warranty. Do not use the outdoor gas fireplace
until all connections have been checked and do not leak.
A gas system MUST be tested yearly, or whenever the LP gas
cylinder is replaced, or any other gas system part.
WARNING: Locate the gas hose out of pathways where
people may trip over it or in areas where the hose may be
subject to accidental damage.
When lighting your outdoor gas fireplace always keep
your face and body as far away from the burner housing
screen as possible.
GAS PRESSURE
Natural Gas
The Natural gas models will have an inlet pressure to the gas valve
from a minimum of 7.0" w.c. (1.743kPa) for the purpose of input
adjustment to a maximum of 10.5"w.c. (2.615kPa).
Propane Gas
The Propane gas models will have a manifold pressure of
approximately 11.0"w.c. (2.739kPa) at the orifice holder with the
inlet pressure to the gas valve from a minimum of 11.0"w.c.
(2.739kPa) for the purpose of input adjustment to a maximum of
13.0"w.c. (3.237kPa).
A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge
connection, is located on the orifice holder.
1. Push in gas control knob slightly and turn clockwise
to "OFF". Note: Knob cannot be turned from "HIGH" to
"OFF" unless knob is pushed in slightly. Do not force.
2. Wait five (5) minutes before attempting to light the burner
from a cold start or when a hot outdoor gas fireplace is relit.
3. Turn knob on gas control counterclockwise to
"HIGH".
4. Push in control knob all the way and hold in. Immediately light
the burner with the piezo ignitor. Continue to hold the control
knob in about one (1) minute after the burner is lit. Release
knob, and it will pop back up. Burner should remain lit. If it
goes out, repeat steps 1 through 4.
LIGHTING INSTRUCTIONS
If knob does not pop up when released, stop and immediately
call your service technician or gas supplier.
If the burner will not stay lit after several tries, turn the gas
control knob to OFF and call your service technician or gas
supplier.
5. Turn gas control knob counterclockwise from
"HIGH" to "MED." or to "LOW".
To Turn Off Gas to Outdoor Gas Fireplace
1. Push in gas control knob slightly and turn clockwise
to "OFF". Do not force.
2. Turn off gas supply to outdoor gas fireplace when not in use.
