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.

Table 3B Concentric Vent Kit Equivalent Vent Lengths
Minimum / Maximum allowable combustion
air and vent piping lengths are as follows:
Combustion Air
= 12 equivalent feet minimum / 100 equivalent
feet maximum
Vent
= 12 equivalent feet minimum / 100 equivalent feet
maximum
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 (CVK3003) = 49 equivalent
feet of piping.
The appliance output rating will reduce by
up to 1.5% for each 25 feet of vent length.

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.
