INSTALLATION
Continued
We recommend that you install a sediment
trap in supply line as shown in Figure 7, page
8. Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and appliance. Locate
sediment trap where trapped matter is not
likely to freeze. A sediment trap traps mois
-
ture and contaminants. This keeps them from
going into heater controls. If sediment trap is
not installed or is installed wrong, heater may
not run properly.
CAUTION: Avoid damage to
gas control. Hold gas control
with wrench when connecting it
to gas piping and/or fittings.
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 appliance. See guidelines
under
Connecting to Gas Sup-
ply
, page 7.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect appliance with its individual
equipment shutoff valve from gas supply
piping system. Pressure in excess of 1/2
psig will damage appliance 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 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 noncorrosive leak detection fluid to
gas joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect log set 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 Fig-
ure 8).
2. Pressurize supply piping system by either
using compressed air or opening main gas
valve located on or near gas meter.
3. Check all joints from gas meter to equip
-
ment shutoff valve for natural gas or
propane/LP supply to equipment shutoff
valve for propane/LP (see Figure 9 or
Figure 10, page 10). Apply noncorrosive
leak detection fluid to all joints. Bubbles
forming show a leak.
4. Correct all leaks at once.
