6.0 CONDENSATE DRAIN
This unit produces liquid condensate in the heat exchanger and venting system as a product of combustion.
Steps must be taken to ensure condensate does not collect in the venting system; therefore, all exhaust piping
must slope back to the boiler a minimum 1/4” per linear foot of vent. Condensate must be drained from the unit
into a household drain.
Check with your municipality, or local gas company to determine if the disposal of
combustion condensate is permitted in your area (e.g. in the
State of Massachusetts
the
condensate must be neutralized prior to entering a drain).
The following are important notes that must be taken into consideration when constructing the condensate drain
system (See Condensate Trap Installation Instructions for further details):
DO NOT
install condensate lines outside. A frozen or blocked drain will cause the condensate to back-up
and leak. This may result in damage to boiler components resulting in a no heat condition; property damage
may also occur.
NEVER
use copper, steel, or galvanized piping in the construction of the condensate system (condensate is
very corrosive and will corrode most metals).
When a condensate pump is used or required, select a pump that is designed for residential furnaces.
Condensate Trap Installation Instructions (see Figure 6-1)
(Note: the Condensate Trap is factory supplied with the boiler and must be field installed)
1.
Attach Corrugated Outlet Tube
– Remove the
Outlet Retaining Nut
and
Outlet Gasket
and slide
components onto the
Corrugated Outlet Tube
– note orientation (gasket should be positioned
approximately 1/8” from the edge of the outlet tube – see Figure 6-1). Press the
Corrugated Outlet Tube
into the
Condensate Trap Outlet
and firmly hand-tighten the
Outlet Retaining Nut
.
2.
Attach to Boiler Condensate Drain (A)
– Ensure the
Ball-float
is placed inside the condensate trap,
position the
Inlet Gasket
in between the condensate trap and boiler condensate outlet (See Figure 6-1).
3.
Attach to Boiler Condensate Drain (B)
– Secure the
Condensate Trap
into place by firmly hand-
tightening the
Inlet Retaining Nut
.
4.
Outlet to Drain
– Route the condensate from the Corrugated Outlet Tube to a household drain, condensate
pump or neutralizer (check with your local authority regarding the disposal of condensate).
Carefully follow the above instructions and the accompanying figure – check to ensure
the condensate trap is secure to the bottom of the boiler and that no strain is placed on it.
Failure to install the condensate trap properly will result in flue gas spillage and leeching of carbon monoxide
emissions into the surroundings resulting in serious injury or death.
