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
2
) openings [a 2" x 5"
(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 fl oor.
• There must be 2" (5 cm) minimum clearance from the fl oor to
ground level of enclosure.
CAUTION: Use only new, black iron or steel pipe.
In ter nal ly-tinned copper tubing may be used in cer tain
areas. Check your local codes. Use pipe of 1/2" di am-
e ter or greater to allow prop er gas vol ume 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 up stream from log set
(see
Figure 13
).
IMPORTANT:
Install equipment shutoff valve in an ac ces si ble lo ca-
tion. The equip ment shutoff valve is for turning on or shut ting 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 seal ant that is resistant
to liquid pe tro leum (LP) gas.
INSTALLATION
Continued
We recommend that you install a sed i ment trap in supply line as shown
in
Figure 13
. Locate sediment trap where it is within reach for clean-
ing. Install in piping system between fuel supply and appliance. Locate
sed i ment trap where trapped mat ter is not likely to freeze. A sediment
trap traps mois ture and con tam i nants. This keeps them from going into
heater controls. If sediment trap is not in stalled 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 fi ttings.
