Condensate Drain - NTI FTG 600 Installation And Operation Manual

FTG

6.0 CONDENSATE DRAIN

The FTG boiler 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 ¼ in. 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.
All tubing, drains and surfaces that come in contact with condensate draining from the
boiler, must be constructed out of corrosion resistant material; copper, steel and
galvanized are not acceptable materials for draining condensate. Failure to abide by this
caution will result in property damage.
Condensate Trap Installation Instructions (see Figure 6-1)
(Note: the Condensate Trap is factory supplied with the boiler and must be field installed)
1. Identify Condensate Trap & Accessories Provided with the Boiler – A Condensate Trap, Gear Clamp
and Support Bracket (c/w screws) are factory supplied with each FTG boiler, and are needed for properly
securing the Condensate Trap to the boiler (see Figure 6-1).
2. Attach to Boiler Condensate Drain – As illustrated in Figure 6-1(a), slide the Condensate Trap inlet fitting
over the Boiler Condensate Drain; use the factory supplied Gear Clamp to secure the Condensate Trap in
place (ensure that the Condensate Trap cannot be pulled off). With the factory supplied screws, fasten the
Support Bracket into place while trapping the top of the Condensate Trap between the Support Bracket and
boiler, thus ensuring the Condensate Trap stays in the vertical position.
3. Prime Condensate Trap – Fill the Condensate Trap with water to prevent flue gases from escaping during
initial firing of the burner.
4. Outlet to Drain – Direct condensate from the outlet of the Condensate Trap to a household drain,
condensate pump or neutralizer (check with your local authority regarding the disposal of condensate). If
necessary connect suitable tubing to the outlet of the Condensate Trap and route it to drain, being careful
NOT to route it higher than the Condensate Trap outlet (see Figure 6-1).
The Condensate Trap must be periodically disassembled and cleaned as part of a regular
maintenance plan. Failure to clean the trap regularly can cause condensate drain blockage
leading to boiler malfunction, property damage and even personal injury.
Carefully follow the above instructions and the accompanying figure – check to ensure
the Condensate Trap is secure 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.
