Installation Items

Before installing heater, make sure you have the items listed below.

external regulator (supplied by installer)

piping (check local codes)

sealant (resistant to propane/LP gas)

equipment shutoff valve *

ground joint union

test gauge connection *

sediment trap

tee joint

pipe wrench

* A CSA design-certified equipment shutoff valve

with 1/8" NPT tap is an acceptable alternative to

test gauge connection. The optional CSA design-

certified equipment shutoff valve can be purchased

from your dealer. See Accessories, page 17.

If installing to a fixed fuel piping system, the

installation must conform with local codes or, in

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 large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.

Installation must include 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 an equipment shutoff valve in an accessible location. 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.

the absence of local codes, with the National Fuel

Gas Code, ANSI Z223.1.

If the heater will be connected to a permanent

gas source, the installer must supply an external

regulator. The external regulator will reduce in-

coming gas pressure. You must reduce incoming

gas pressure to between 11" and 14" of water. If

you do not reduce incoming gas pressure, heater

regulator damage could occur. Install the external

regulator with the vent pointing down as shown

in Figure 12. Pointing the vent down protects it

from freezing rain or sleet.
