for the U.S. and/or canada, the installation of this appliance must
comply with local and/or Provincial codes or, in the absence of
these codes,
•
With the (U.S.) National Fuel Gas Code, ANSI Z223.1 –
Latest Edition (for LP-Gas operation, Model, MH125LP),
and with the (U.S) Standard for the Storage and
Handling of Liquefied Petroleum Gases, ANSI/NfPA 58
(for LP Gas operation, Model MH125LP, HS125LP), or
•
with the current (Canadian) CAN/CGA B149.1 AND
B149.2 INSTALLATION CODES.
This heater (including hose and regulator assembly if applicable)
must be inspected before each use and at least annually by a
qualified service person. If the hose for Model MH125LP shows
evidence of excessive abrasion or wear, or if the hose is cut, it
must be replaced prior to the heater being put into operation.
The replacement hose assembly shall be that specified by the
manufacturer. See the parts list.

LOCATION

The heater (and LP-Gas supply cylinder if applicable) must be
located on a hard, flat, level surface to minimize the risk of
accidental tipping. If an LP Gas supply cylinder is used (i.e. with
Model MH125LP), the cylinder should be adequately restrained to
prevent accidental tipping. dO nOt operate this heater with
the supply cylinder in any other than the upright position.
This appliance must be installed only in locations where the
potential for physical damage to the appliance (i.e., due to
physical contact) is reduced to a minimum.
The installer must inform the owner/operator of this appliance
that precautions must be taken to protect the appliance from
physical damage.
This appliance produces radiant heat. Therefore, it must be located
at least six feet away from any LP-Gas container and must not be
directed toward any LP-Gas container within 20 feet.
The heater must be installed in a location such that it will not be
exposed directly to water spray, rain, and/or dripping water.
Use of this heater in a draft/windy area decreases its efficiency. If
possible, operate the unit in a draft free area.
The appliance area must be kept clear and free from combustible
materials, gasoline and other flammable vapors and liquids.

PIPING

For Model MH125lp (for use with lp‑gas)
This model may be connected to a self-contained LP-Gas
supply system using the hose and regulator assembly
supplied with the appliance, OR, it may be connected to a
permanently installed LP-Gas supply system.
If connected to a self-contained LP-Gas supply system, the
hose assembly must be inspected prior to each use of the
Gas-Fired Infra-Red Portable Construction Heater
heater. If it is evident that there is excessive abrasion or wear,
or if the hose is cut, it must be replaced prior to the heater
being put into operation.
If connected to a self-contained LP-Gas supply system, the
cylinder must have no less than a minimum capacity of
40 pounds and no more than a maximum capacity of 100
pounds of LP-Gas. DO NOT connect this appliance to a
cylinder having less than a nominal 40 pounds capacity of
LP-Gas.
WARNING
NEVER USE A fORK LIfT TRUcK TYPE
cYLINDER.
The connection of Model MH125LP to an LP-Gas cylinder must
be made in a well ventilated area using the regulator and hose
assembly supplied with the appliance. dO nOt attempt to
adjust this regulator. It has been preset at the factory to provide
safe and proper operation of the appliance. Use a 7/8" open end
wrench to connect the POL fitting (supplied with the LP regulator)
to the LP-Gas cylinder. Turn the POL nut in a counter-clockwise
direction (left hand thread) until tight. dO nOt use pipe
compound on pOl threads.
The heater must be located at least six feet away from any
LP-Gas cylinder and must not be directed toward any LP-Gas
cylinder within 20 feet. If more than one heater is used, they
and the supply cylinders must be separated by at least 20
feet. Check local codes.
The gas supply must be turned off at the LP-Gas supply
cylinder when the heater is not in use.
When the heater is to be stored indoors, the connection
between the LP-Gas supply cylinder and the heater must be
disconnected and the cylinder removed from the heater and
stored in accordance with chapter 5 of the Standard for the
Storage and Handling of Liquefied Petroleum Gases. ANSI/
NFPA 58 (U.S.) OR CAN/CGA B149.2 (Canada).
If connected to a permanently installed LP-Gas supply system,
the system requires the use of a two-stage gas regulator
assembly which is normally provided by your LP Gas dealer
as part of the LP-Gas supply system. Consult with your local
LP Gas dealer for details concerning proper equipment and
installation.
Before attempting to ignite the appliance, all gas fittings and
connections must be thoroughly checked for gas leaks. Apply a
small amount of a mild soap and water solution to all fittings and
connections and observe for escaping bubbles. If any leaks are
detected, shut off the gas supply to the appliance immediately.
Wait a minimum of five minutes, repair the leak(s) and retest for
leakage. Dry all fittings and connections after leak testing.
