Installation Instructions and Owner’s Manual
Unvented Liquid Propane Fired Room Heater
WARNING:
Never use an open flame to check for
a gas leak. Apply a mixture of liquid soap and water
to all joints. Bubbles forming show a leak. Correct
all leaks at once.
PRESSURE TESTING GAS SUPPLY PIPING
SYSTEM
High Pressure
Test pressure in Excess of ½ psig (3.5kPa)
1. Disconnect appliance with its appliance main
gas valve (control valve) and equipment shutoff
valve from gas supply piping system. Pressures
in excess of ½ psig will damage heater regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either using
compressed air or opening main gas valve on
or near gas meter.
4. Check all connections and joints in gas supply
piping system. Apply mixture of liquid soap and
water to gas joints. Bubbles forming show a
leak.
5. Correct all leaks at once.
6. Depressurize and relieve pressure in supply
piping system.
7. Reconnect heater and equipment shutoff valve
to gas supply.
8. Reconnected fittings must be checked for leaks
in next section.
Low Pressure
Test Pressure Equal To or Less Than ½ psig (3.5 kPa)
1. Close equipment shutoff valve (see figure 12).
2. Pressurize supply piping system by either using
compressed air or opening propane/LP supply
valve.
3. Check all joints from the propane/LP supply
valve to equipment shutoff valve (see figure
13). Apply mixture of liquid soap and water to
gas joints. Bubbles forming show a leak.
4. Correct all leaks at once.
5. Depressurize and relieve pressure from supply
piping system.
Pressure Testing Heater Gas Connections:
1. Make sure that the heater supply piping sys
-
tem is connected and has been leak tested as
described above.
2. Make sure control knob of heater is in OFF
position.
3. Open equipment shutoff valve (see figure 12).
4. Open propane/LP supply valve.
5. Check all joints from equipment shutoff valve
to control valve (see figure 13). Apply mixture
of liquid soap and water to gas joints. Bubbles
forming show a leak.
6. Correct all leaks at once.
7. Light heater (see
Operating Your Heater
, page 10.
8. Turn off heater (see
To Turn OFF Gas to
Appliance
, page 10.
9. Replace lower front panel.
