Heater Expansion
It is a normal condition that during heat-up and cool-down a tube
heater will expand and contract. Allowances for heater expansion
must be made in the gas connection, venting and combustion air
ducting. Improper installation, alteration, or adjustment can result in
WARNING
Venting
Inadequate venting of a heater may result in asphyxiation, carbon
monoxide poisoning, injury or death. This heater may be directly or
indirectly vented from the space. Venting must be in accordance with
all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in USA;
B149.1 in Canada) and as indicated in this manual. Refer to Sections 11 & 12
Gas Connection
Improper installation, connection, or adjustment can result in property
damage, toxic gases, asphyxiation, injury or death. Use the approved
Type 1 hose gas connector supplied with the heater to connect the
heater to the gas supply. The gas supply must be connected tested in accordance with all lo-
cal, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in USA; B149.1 in Canada)
and as indicated in this manual. Refer to Section 13

WARNING
WARNING
Start-Up ‘SMOKE’ Condition
During start up, the heating of material coatings used in the production process of tubes and
reflectors will create smoke during the initial period of operation. This condition is normal and
temporary .
Ensure that there is sufficient ventilation to adequately clear any smoke from the space.
Notify site and safety personnel to ensure that alarm systems are not unduly activated.
WARNING
Tube “GLOW”
It is a normal condition that the combustion tube (1st tube) can appear to “glow red”. For inputs
up to 150,000 Btuh, the top surface of the tube can appear red where heat is trapped between
the reflector and the tube. The stainless steel tube used for inputs 175,000 and greater ap-
pears to entirely glow red. The tube material is designed into the heater because it can with-
stand the high temperature of combustion, and the “red glow” is a normal occurrence.
