Sunpak® Infrared Heaters
8
Fire Sprinklers
Fire Sprinklers must be located at an appropriate
distance from each heater to avoid accidental
activation of the sprinkler. Ethylene glycol or
propylene glycol must never be used in fire sprinkler
systems where heaters are present as these
substances may become flammable when heated. A
fire sprinkler professional must be consulted when
heaters are installed where fire sprinklers are
present to insure that heaters and the fire sprinkler
system are properly integrated. Specific guidelines
can be found in NFPA 13 regarding design and
specifications for Fire Sprinkler Systems near
heaters.
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.
CAUTION
Sharp Edges
Every effort has been made to remove sharp
edges from this heater; however care should
be taken to avoid injury when reaching inside
the heater during installation and when
servicing this unit.
Electrical
1. Provide only 24 VAC with a NEC Class 2 transformer to
the heaters. Each heater requires approximately 20VA
or 0.8 amps. When multiple heaters are connected to
one transformer, the transformer must be sized to
accommodate the entire load. A transformer must
NEVER be located inside the heater control
compartment.
2. Control wire used to electrically connect one or more
heaters together must have adequate capacity and
insulation temperature rating for the total connected
load. Use at least 18 GA wire up to 50 feet from heater
to transformer or wall switch. Use a minimum of 16 GA
wire for over 50 feet distance.
3. If any of the original wire supplied with the appliance
must be replaced, it must be replaced with wiring
material having a temperature rating of at least 105
degrees Centigrade.
WARNING
Electrical Shock Hazard
Disconnect electrical power and gas supply before
servicing
This heater must be connected to a properly
grounded electrical source.
Failure to follow these instructions can result in
death or electrical shock.
