Natural Gas Supply Information
Natural Gas is lighter than air.
- In its natural state, Natural Gas has no odor,
but for your safety an odor that smells like
rotten cabbage has been added.
- The user of this heater must provide the
Natural Gas supply and all fittings to properly
install the heater.
- The Natural gas supply should be able to
provide a minimum of 150 cubic feet of gas
per hour for each heater being used.
- Consult with your Natural Gas supplier for the
proper sizing of all gas lines.
- You must regulate the Natural Gas supply
down from the minimum of 5 inches of water
column to a maximum of 1/2 PSI.
Connecting Heater To Gas Supply
NOTE: Heater is manufactured for use with
Natural Gas (NG) only. DO NOT attempt to
convert to any other gas. Such modifications
are dangerous and will void the warranty.
1 . Provide the Natural Gas supply system
(See Gas Supply Information Above).
2. Connect all plumbing and fittings to the
low-pressure Natural Gas sources.
3. This source must be regulated to a maximum
1/2 PSI.
4. The piping must be a 3/4 inch inside diameter
minimum and not be over 10 feet in length.
5. Line up the female threaded end of the hose
with the inlet connector on the heater base
and tighten.
6. Slowly open valve at Natural Gas supply.
7. Check for leaks at all connections.
Checking For Leaks
- To check for leaks, make up a 50/50 solution
of dish soap and water. Apply this solution
to all gas connections. If bubbles appear,
there is a leak. If a leak is found, turn off
the gas supply, and re-connect the leaking
connection.
The installation of this heater must meet all
local codes and/or gas utility requirements. In
the absence of local codes, the National Fuel
Code ANSI Z223.1 should be followed.
- The minimum clearances to any combustible
construction materials must be maintained at
all times (See Page 2).
- Inspect the heater before each use, and at
least annually by a qualified service person.
I A CAUTION I Natural Gas (NG) is safe to
�---� use when properly handled.
Careless handling of NG could result in a
fire and or an explosion.
