Description
The INFRA-REZ
®
heater Model TRP packaged
tubular radiant heaters are available in BTUH in-
puts from 30,000 to 100,000. All sizes are avail-
able for use with natural or propane gas. Model
TRP heaters provide full input rate heating ca-
pacity to 2,000 feet elevation. INFRA-REZ
®
tu-
bular radiant heaters are engineered to provide
quiet, reliable, energy-efficient comfort heating
for both spot and space applications.
The Model TRP heater is designed with a burner/
control box housing an inshot burner(s) and con-
trols. The burner is equipped with a blower for
supplying combustion air and a direct spark
burner ignition (DSI) system. Controls in the box
include an ignition control board, a pressure
switch to verify combustion airflow, and a redun-
dant single-stage gas valve.
A series of highly emissive tubes with polished
reflectors provide for the transfer of radiant heat.
For maximum efficiency, the exhaust end of all
systems is equipped with an aluminized steel
turbulator strip.
Combustion air can either come from the heated
space or, when a system is specified to use out-
side air, it can be piped from the outside through
a separated combustion air/vent system. The fol-
lowing applications require outside combustion
air: (1) if the building atmosphere has negative
pressure; (2) if the building atmosphere is dirty or

WARNING: Gas-fired appliances are not
designed for use in hazardous
atmospheres containing flammable
vapors or combustible dust, or
atmospheres containing chlorinated or
halogenated hydrocarbons.
Installations in public garages or airplane
hangars are permitted when in
accordance with ANSI Z83.6B and NFPA-
406 and 88 Codes or CAN-B149 Codes and
enforcing authorities.
NOTE: Not certified for residential use.
dusty; (3) if the building atmosphere contains sub-
stances that will cause toxic gas when combined
with flame or flue products; or (4) if the heater is
being installed in a tightly closed room that does
not provide required air for combustion.
Venting to the outdoors may be either vertical or
horizontal. Dual venting of two units is permis-
sible when using a specially designed optional
Dual Vent Kit. In suitable applications, Model TRP
systems may be operated with an indoor vent
cap. When the unit includes a weatherizing op-
tion, it may be installed in outside areas such as
courtyards or patios.
The Model TRP tubular packaged heater sys-
tems are shipped in a single package that does
not require field assembly. (Sizes 50 and 100 are
hinged for packaging and handling purposes.)
Standard features such as built-in hangers for
chain suspension, crimped tube connections, and
a terminal board for thermostat connection are
designed to facilitate installation.
These tubular radiant packaged heaters are ap-
proved for use in the United States and Canada
by the Canadian Standards Association (CSA).
The manufacturer provides a five-year limited
warranty on the burner and a ten-year limited
warranty on all tubes. (See Warranty Form for
terms and limitations.)
