REMOTE PROPANE/LP GAS SUPPLIES AND ENCLOSURES
If appliance is to be permanently connected to a gas piping system
from a remote supply tank, installation must be in accordance with
local codes or, in absence of local codes, with the National Fuel Gas
Codes ANSI Z223.1/NFPA 54.
Enclosures may be used to conceal propane/LP supply tanks and
must be constructed to meet the following minimum construction
requirements:
• An enclosure must have either one open side or at least four
opposing vent openings, top and bottom, which meet minimum
requirements for size and location (see Figure 12).
• Each opening must provide a minimum or 1/2 square inches (3,23
cm 2 ) of open area for each pound propane/LP contained in enclosed
supply tank.
Example: A full enclosure for a 20 pound propane/LP tank must
have at least four, 10 square inches (65 cm
(5 x 13 cm) square].
• The top openings must be 180° opposing and be placed at valve
level.
• The bottom openings must be 180° opposing and be placed 5"
(12.7 cm) above bottom floor.
• There must be 2" (5 cm) minimum clearance from the floor to
ground level of enclosure.
CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in certain
areas. Check your local codes. Use pipe of 1/2" diam-
eter or greater to allow proper gas volume to heater.
If pipe is too small, undue loss of volume will occur.
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 log set (see Figure 13).
IMPORTANT: Install equipment shutoff valve in an accessible loca-
tion. The equipment shutoff valve is for turning on or shutting off
the gas to the appliance.
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.

We recommend that you install a sediment trap 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 appliance. Locate
sediment trap where trapped matter is not likely to freeze. A sediment
trap traps 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.

and/or fittings.
* Purchase the optional shutoff valve from your dealer.
** Minimum inlet pressure for purpose of input adjustment.
