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

Vent

Installation & Operation Manual

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° elbows + (2) 45° elbows + (1) concentric vent kit (CVK3003) = 49 equivalent feet of piping.

NOTICE

The appliance output rating will reduce by

up to 1.5% for each 25 feet of vent length.

Removing from existing vent

Follow the instructions in Section 1, page 12 of this manual when removing a water heater from an existing vent system.

Vent and air piping

Vent and air system:

Installation must comply with local NOTICE requirements and with the National Fuel

Gas Code, ANSI Z223.1 for U.S. installations or CSA B149.1 for Canadian installations.

You must also install air piping from outside to the water heater air intake adapter. The resultant installation is direct vent (sealed combustion).

You may use any of the vent/air piping methods covered in this manual. Do not attempt to install the Armor water heater using any other means.

NOTICE

or vent piping is not authorized.

 

￿WARNING

DO NOT mix components from different systems. The vent system could fail, causing leakage of flue products into the living space. Use only approved stainless steel, PVC or CPVC pipe and fittings. For PVC/CPVC use with primer and cement specifically designed for the material used.
