To Gas Control
Installation must include an equipment shutoff
valve, union and plugged 1/8" NPT tap. Locate
NPT tap within reach for test gauge hook up.
NPT tap must be upstream from heater
(see
Figure 13).
IMPORTANT:
Install equipment shutoff valve
in an accessible location. The equipment
shutoff valve is for turning on or shutting off
the gas to the appliance.
Check your building codes for any special
requirements for locating equipment shutoff
valve to fi replaces.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could
result in clogged heater valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
CAUTION: Avoid damage to
gas control. Hold gas control
with wrench when connecting
it to gas piping and/or fi ttings.
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 fl ame to check for a leak.
Apply a noncorrosive leak detec-
tion fl uid 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 14.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
volume will occur.
We recommend that you install a sediment
trap (not supplied with log set) in supply line
as shown in
Figure 13
. Locate sediment trap
where it is within reach for cleaning. Install
in piping system between fuel supply and
heater. Locate sediment trap where trapped
matter is not likely to freeze. A sediment trap
captures moisture 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.
