Condensate disposal
Condensate drain
1. The AQUAS Fire Tube boiler is a high efficiency
appliance that produces condensate.
2. The condensate trap has a 1/2" outlet connection pipe for
tubing.
3. Slope condensate tubing down and away from the
boiler into a drain or condensate neutralizing filter.
Condensate from the AQUAS Fire Tube boiler will be
slightly acidic (typically with a pH from 3 to 5). Install a
neutralizing filter if required by local codes.
A Neutralizer Kit (#100157721) is available from the
factory (FIG. 9-1).
4. Do not expose condensate line to freezing temperatures.

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 boiler tee, resulting in potential
water damage to property.
5. A condensate removal pump is required if the boiler is
below the drain. When installing a condensate pump,
select one approved for use with condensing boilers 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 drain
switch inside the boiler (see FIG. 10-3 on page 55).
