WARNING
Suspension Hazard
Mounting kits and hanging supports must
be able to withstand a minimum working
load of 75 lbs (33 kg). Failure of the
supports can result in death.
Local codes regarding head clearance
requirement must be observed.
Heater Mounting and Support
Heaters shall be mounted in a fixed position independent
of gas and electrical supply line. Hangers and brackets
shall be of noncombustible material.
Heaters subject to vibration shall be provided with
vibration isolating hangers.
Suitable materials for hanging infrared heaters are steel
pipe, steel channel, or fabricated hangers of at least 16-
gage material. Hanger and brackets must be secured with
adequate anchor to a secure structure using good
building practices. Additional bracing to protect against
seismic forces may be required in seismically active
areas. Never mount heater to a moving object such as a
trailer, motor home boat, etc.
Gas Piping
1.
A minimum pipe size of ½” is required for inlet piping. A
½” leaver handled shut-off gas cock should be installed
within 6 feet of the appliance for servicing and as
emergency shutoff to the unit.
2.
Check with local and state plumbing and heating codes
regarding sizing of gas lines.
3.
All gas pipe connections to the heater(s) must be sealed
with a gas pipe compound resistant to liquefied
petroleum gases.
4.
Installation of a drip leg or sediment trap in the gas
supply line going to each heater is required to minimize
the possibility of any loose scale or dirt within the gas
supply line from entering the heater’s control system.
5.
When checking for gas leaks, do not use an open flame.
Use a soap and water solution.
6.
For gas supply line pressures in excess of ½ psig,
consult the factory or your local representative.
7.
Installation of 1/8” N.P.T. plugged tap accessible for test
gage connections is required upstream of the gas
supply connections to the heater.
8.
Never use pipe sealing compound on brass to brass
flared fittings.
Electrical
1. The Power Adapter included provides 7.5 VDC to the
heater. The Power Adapter has a 24 inch wire lead
connected to the main heater module by two slide
connectors (see page 10). The low voltage connection
can be extended using 18 GA outdoor rated thermostat
wire up to 50 feet. For distances greater than 50 feet 16
GA or larger wire will be necessary.
2. If any of the original wire supplied inside the appliance
must be replaced, it must be replaced with wiring material
having a temperature rating of at least 105 degrees
Centigrade.
