VENTING
All venting must be in accordance with all applicable codes
1. The maximum allowable length of vent pipe is 30 ft. (9.14 meters). This length includes
the combination of inlet air vent for combustion and exhaust venting. THE RADIANT
TUBE IS NOT INCLUDED IN THIS MEASUREMENT. For every 90-degree elbow in
the vent system, 5 ft. (1.5 meters) must be deducted from the total allowable length.
Horizontal venting must be installed with a 1/4” (3.5 cm) per foot downward slope.
2. The exhaust vent terminal must be installed not less than 7 ft. (2.1 meter) above grade.
Fresh air seamless air intake duct and screened wall caps are available from your Easy
Radiant Works supplier. When installed in a building with a negative air condition,
combustion air from outside the negative area is mandatory. Combustion air wall cap
shall not be installed less than 3 ft. (.9 meters) above grade.
3. Type “B” vent must be used for that portion of the vent that passes through a
combustible. For through the wall venting, the exhaust vent terminal supplied by Easy
Radiant Works MUST be used. The tip of the vent terminal must be a minimum of 16”
(40 cm) off the wall. For roof venting a suitably approved Belmont type rain cap must be
used
.
The use of any wall vent terminal other than that supplied by E

will void warranties. E

accepts no responsibility for damages
created by other vent terminals. Exceeding the allowable lengths noted may create
condensation problems and will void Design Certification and the heater warranty.
4. If vent pipe with a slip fit connection is used, it must be mechanically secured.
Uninsulated vent pipe must not run through unheated spaces.
5.
Venting must be supported every 3 ft. (.9 meters). Vents for products of combustion shall
not terminate less than 6 ft. (1.8 meters) from inlet air of any other appliance or be less
than 3 ft. (.9 meters) from any building opening or directly above a gas utility meter.
6.
The Ez-Duzzit tube system has been approved for vented and un-vented applications.
When installed un-vented it must be electrically interlocked to an exhaust fan with an air
proving switch. The exhaust fan must provide exhaust in the amount of 300 c.f.m. for
every 100,000 BTU input in Canada and the amount of 400 c.f.m. for every 100,000 BTU
input in the USA. When installed un-vented provision must be made to supply adequate
combustion air from outside the space. Combustion air openings must be in the amount
of one (1) square inch (2.5 sq.cm) or more of free area for each 10,000 BTUH. When
installed vented, installations must comply with all governing codes.
7. When installed in a large and adequately ventilated space (agricultural building used only
for brooding purposes) the heater may be installed un-vented without interlocking, and
may be operated by discharging the combustion products directly into the space, subject
to the approval of the authority having jurisdiction and provided that the maximum input
of the appliance does not exceed 20 BTUH/ft
3
(0.2 kW/m
3
) of the space in which the
heater is located. An appliance designed to produce a controlled atmosphere need not be
subject to these conditions.
