VENTING 

1.

 

The Easy Radiant 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 or 
more of free area for each 10,000 BTUH.  When installed vented, installations 
must comply with all governing codes.  

2.

 

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. 

3.

 

All venting material shall be CGA/AGA approved and minimum 4” diameter. 

 

4.

 

The maximum allowable length of vent pipe is 60 feet.  This length includes the 
combination of inlet air vent for combustion and exhaust venting.  THE 
RADIANT TUBE  IS NOT INCLUDED IN THE MEASUREMENT.  For every 
90-degree bend in the system, 5 feet must be deducted from the total.

   

5.

 

When venting through a combustible wall or roof, type “B” vent must be used for 
that portion of the vent that passed through the wall or roof.  For wall venting, the 
manufacturer’s approved vent spout or exhaust cap must be used. S ee page 20. 
All models vented through a side wall to be connected to a 4” diameter type “B” 
or “L” vent. The maximum equivalent vent length is 30 ft. For each 90 degree 
elbow 5 ft must be deducted from the equivalent maximum. 

The use of any wall 

vent terminal other than that supplied by E

warranty. 

6.

 

All vent pipe used with a slip fit connection must be mechanically secured, and all 
vents must be supported every 3 feet. 

7.

 

Vent pipe of single wall construction shall not run through unheated spaces unless 
insulated. 

8.

 

All vent pipes longer than 10 feet must be insulated or have insulated type vent 
materials. 

9.

 

Vents for products of combustion shall not terminate less than three (3) feet from 
a combustion air inlet of any other appliance, or be less than three (3) feet from a 
building opening or be directly above a gas utility meter or service regulator. 

10.

 

The exhaust vent terminal must be installed not less than 7 feet above grade. 

11.

 

Air intakes terminals shall not be located less than three (3) feet above grade.

When located in a building with a negative air condition, or in a dusty or 

dirty atmosphere such as a wood working shop, poultry barn or foundries, 
combustion air from outside the negative or dirty area to the burner is mandatory.  
The combustion air supply should be minimum 4-inch diameter seamless air duct, 
connected to fresh air adapter provided on combustion air blower.  All joints or 
seams shall be sealed to prevent leaks.
