CHECKING GAS CONNECTIONS
WARNING: Test all gas piping
and connections, internal and
external or unit, for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an open
flame to check for a leak. Apply a
noncorrosive leak detection fluid
to all joints. Bubbles forming show
a leak. Correct all leaks at once.
CAUTION: Make sure exter-
nal regulator has been installed
between propane/LP supply and
heater. See guidelines under
Con-
necting to Gas Supply
, page 9.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect heater with its appliance main
gas valve (control valve) and equipment
shutoff valve from gas supply piping sys-
tem. Pressures in excess of 1/2 psig will
damage heater regulator.
2. Cap off open end of gas pipe where equip
-
ment shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas, opening main gas valve
located on or near gas meter for natural
gas or using compressed air.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection fluid to
gas joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff
valve to gas supply. Check reconnected
fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1.
Close equipment shutoff valve (see Figure 8).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas, opening main gas valve
located on or near gas meter for natural
gas or using compressed air.
3. Check all joints from gas meter to equip
-
ment shutoff valve (see Figures 9 and 10).
Apply noncorrosive leak detection fluid to
gas joints. Bubbles forming show a leak.
4. Correct all leaks at once.
PRESSURE TESTING HEATER GAS
CONNECTIONS
1.
Open equipment shutoff valve (see Figure 8).
2. Open main gas valve located on or near
gas meter for natural gas or open propane/
LP supply tank valve for propane/LP gas.
3. Make sure control knob of heater is in the
OFF position.
4.
Check all joints from equipment shutoff valve
to control valve (see Figures 9 and 10). Ap-
ply noncorrosive leak detection fluid to gas
joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light heater (see
Operation
, page 14).
Check all other internal joints for leaks.
7. Turn off heater (see
To Turn Off Gas to
Appliance
, page 15).
