CHECKING GAS CONNECTIONS

WARNING: Test all gas piping

and connections, internal and

external to 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 detec-

tion 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

ﬁreplace. See guidelines under

Con-

necting to Gas Supply

, page 16.

PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)

1. Disconnect appliance with its appliance main

gas valve (control valve) and equipment shut-

off valve from gas supply piping. Pressures

in excess of 1/2 psig will damage ﬁreplace

regulator.

2. Cap off open end of gas pipe where equipment

shutoff valve was connected.

3. Pressurize supply piping system by either

opening propane/LP supply tank valve for

propane/LP gas or 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 a 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 25).
2. Pressurize supply piping system by either

opening propane/LP supply tank valve for

propane/LP gas or opening main gas valve

located on or near gas meter for natural gas,

or using compressed air.

3. Check all joints from gas meter for natural or

propane/LP supply to equipment shutoff valve

(see Figures 26 and 27). Apply a noncorrosive

leak detection ﬂuid to gas joints. Bubbles

forming show a leak.

4. Correct all leaks at once.
