Installation & Operation Manual

Start-up
(continued)
Use materials approved by the authority
having jurisdiction. In the absence of other
authority, PVC and CPVC pipe must comply
with ASTM D1785 or D2845. Cement and
primer must comply with ASME D2564 or
F493. For Canada use CSA or ULC certified
PVC or CPVC pipe, fittings, and cement.
NOTICE
NOTICE
To allow for proper drainage on large
horizontal runs, a second line vent may
be required and tubing size may need to
increase to 1 inch.
The condensate line must remain
unobstructed, allowing free flow of
condensate. If condensate is allowed to
freeze in the line or if the line is obstructed in
any other manner, condensate can exit from
the condensate trap vent opening, resulting
in potential water damage to property.
The stainless steel retaining ring must be
installed between the rubber sealing gasket
and the compression fitting (FIG. 11-1).
The compression fitting must be tightened.
The condensate trap must have the float
ball (FIG. 11-1) in place during all times
of appliance operation to avoid flue gas
emission from the condensate drain line.
Failure to ensure the float ball is in place
could result in severe personal injury or
death.

WARNING

Condensate Trap
Condensate drain
1. This appliance is a high efficiency appliance that produces
condensate.
2. The provided condensate trap is equipped with a ball
that acts as a seal against harmful flue gases escaping
in case there is no condensate in the trap. If this ball is
not present, flue gases may be able to pass through the
trap when there is no condensate present, resulting in an
unsafe environment. It is important to check and make
sure the ball is located in the trap, acting as a seal against
flue gases.
3. Connect the condensate trap to the condensate hoses
located on the back of the unit hear the bottom. Use
the hose clamps to secure the connection. Connect the
two-pin molex provided with the condensate trap to the
mating connector on the rear of the appliance.
4. Slope condensate tubing down and away from the
appliance into a drain or condensate neutralizing filter.
Condensate from the Armor water heater will be slightly
acidic (typically with a pH from 3 to 5). Install a
neutralizing filter if required by local codes.
A Neutralizer Kit is available from the factory.
5. Do not expose condensate line to freezing temperatures.
6. Use only plastic tubing or piping as a condensate drain
line (FIG. 11-1).
7. A condensate removal pump is required if the appliance
is below the drain. When installing a condensate pump,
select one approved for use with condensing water heaters
and furnaces. The pump should have an overflow switch
to prevent property damage from condensate spillage.
The switch should be wired in series with the blocked flue
switch inside the appliance.
