venting

Requirements for installation in 

Canada

1.  Installations must be made with a vent pipe system 
 

certified to ULC-S636.

 

IPEX is an approved vent manufacturer in Canada 

 

supplying vent material listed to ULC-S636.

2.  The first three (3) feet of plastic vent pipe from the 
 

appliance flue outlet must be readily accessible for visual 

 inspection.

3.  The components of the certified vent system must not be 
 

interchanged with other vent systems or unlisted 

 

pipe/fittings.  For concentric vent installations, the inner 

 

vent tube must be replaced with field supplied certified 

 

vent material to comply with this requirement.

4.  The 3 and 4" Concentric Vent Kit available from 
 

Lochinvar (see Section 4 – 

Sidewall Termination – 

 

Optional Concentric Vent

) and the 3 and 4" Concentric 

 

Vent Kit available from IPEX are both approved for use 

 

on the Armor water heater.  Both kits are listed to the 

 

ULC-S636 standard for use in Canada.

Equivalent Vent Lengths

Minimum / Maximum allowable combustion 

air and vent piping lengths are as follows:

Combustion Air

Vent

 = 12 equivalent feet minimum / 100 equivalent feet

Table 3A 

Air Intake/Vent Piping Sizes

Sizing

The Armor water heater uses model specific combustion air 
intake and vent piping sizes as detailed in Table 3A below.

Increasing or decreasing combustion air 
or vent piping sizes is not authorized, 
unless referenced in manual..

 NOTICE

When determining equivalent combustion air and vent length, 
add 5 feet for each 90° elbow and 3 feet for each 45° elbow. 

EXAMPLE:

  20 feet of PVC pipe + (4) 90° (2) 45° 

(1) concentric vent kit (100140484) = 49 equivalent 
feet of piping.
