GAS SUPPLY
•
The LP-gas cylinder(s) used must
be constructed and marked in
accordance with the specifications
for LP-gas cylinders of the U.S.
Department of Transportation
(DOT).
•
Use only VAPOR WITHDRAWAL
propane supply. If there is any
question about vapor withdrawal,
ask your propane dealer.
•
The installation of the heater must
conform to local codes or, in the
absence of local codes, with the
National Fuel Gas Code, ANSI
Z223.1.
•
This heater is designed to operate
with an inlet pressure of 11 W.C.
(.40 PSIG, 2.8 kPA). Do not install
directly to a propane (LP) gas tank
or cylinder.
•
The supply line must be equipped
at the cylinder with a listed
low pressure propane (LP) gas
regulator set to deliver the
specified pressure. The high
pressure propane (LP) gas line
between the propane (LP) gas
supply source and the regulator
must be equipped with an excess
flow valve to limit the escape of
fuel in case of a break in the line.
Observe these operating
precautions:
•
Due to high temperatures, the
heater should be located out of
traffic and away from furniture and
draperies.
•
Children and adults should be
alerted to the hazard of high
surface temperature and should
stay away to avoid burns or
clothing ignition.
•
Young children should be carefully
supervised when they are in the
same room with the heater.
•
Do not place clothing or other
flammable material on or near the
heater.
•
Installation and repair should be
done by a qualified service person.
The heater should be inspected
before use and at least annually by
a professional service person.
•
WARNING: Any change to this
heater or its controls or attempts
to clean the catalytic pad can be
dangerous.
•
The safety grill, if removed for
servicing, must be replaced prior
to operating the heater. DO NOT
OPERATE WITH DUST SHIELD
COVER IN PLACE!
•
IMPORTANT: The operation of
the heater is such that, on initial
lighting from cold start, a slight
odor of gas may be noticed for
a short period of time — this is
normal. If odor persists, shut off
heater and have it serviced.
•
IMPORTANT: REMOVE DUST
SHIELD BEFORE USE.
•
Do not attempt to clean catalytic
pad. Follow cleaning instructions
accompanying heater.
Fuel
•
This heater is designed for use with
HD-5 propane (LP) gas only. Do not
attempt to convert it to use with other
gases or liquid fuels. Use of any gases
other than HD-5 propane (LP) gas may
cause damage to the catalytic heating
element.
Locations
•
Refer to Specifications table on page 3 for
minimum clearances from combustibles.
IMPORTANT:
When heater is installed
using the feet directly on carpeting, tile,
or other combustible material other
than wood flooring, the heater must
be installed on a metal or wood panel
extending the full width and depth of
the heater.
•
This Heater may be used in a
recreational enclosure or temporary
construction work enclosure with a
remote refillable propane (LP) gas
cylinder ONLY when the cylinder is
located outdoors and the heater is
used with Enerco Hose No. F271161,
F271161-60, and F271161-144.
