HE Series Infrared Gas Heater Installation and Operation Manual
WARNING
11. FLUE VENTING
Inadequate venting of a heater may result in asphyxiation, carbon monoxide
poisoning, injury or death. This heater must be connected to a vent to remove
products of combustion from the space. Seal all vent connections with high
temperature sealant. Venting must be in accordance with all local, state, provin-
cial, and national codes (ANSI Z223.1/NFPA 54 in USA) and as indicated below
in this manual.
This heater must be vented directly to the outside. The system must not be operated with-
in a negative air condition. Ensure adequate air supply to the space to ensure there is no
negative air condition (negative pressure in the space being heated).
This gas appliance must not be connected to a chimney flue serving a separate solid - fuel
burning appliance.
GENERAL FLUE VENTING REQUIREMENTS
It is the sole responsibility of the installer to adhere to all current local codes and/or ANSI
Z223.1 latest editions for all venting requirements, and practices.
It is a normal condition that during heat - up and cool - down a tube heater will expand and con-
tract. Allowances for heater expansion must be made in the venting . Improper installation can
result in property damage, injury or death.
• This heater has a positive vent pressure
•
A vent termination cap is recommended for use with horizontal side wall vent
•
All vent pipe and adapters will be supplied locally by others
• Vent pipe must be minimum 26 gauge single wall type “ C ” vent pipe of 4” (10 cm) diameter
except that portion of vent passing through the wall or roof shall be 4” type “ B ” vent
•
A minimum 12 inch (30 cm) length of minimum 26 gauge single walled 4” (10 cm) diameter
“ C ” vent pipe is to be installed on the swaged end of the tube before any vent elbow is fitted.
•
Seal all vent connections with high temperature sealant.
Vent connections
must be secured with three (3) #8 sheet metal screws uniformly spaced around the circum-
ference of the vent pipe.
•
When the vent pipe passes through a cold or unheated area where the ambient temperature
is likely to produce condensation of the flue gases, the vent pipe will be insulated with a suit-
able material as approved and specified by the insulation manufacturer to withstand tem-
perature up to 460°F (238°C).
•
The vent system must always be adequately supported to prevent sagging.
