For vent pipe installation refer to the vent pipe manufacturers instructions.
• Condensate drain is needed when horizontal vent
lengths are less than 10 feet (3 m).
• Do not place condensate drain where freezing may
occur.
• Condensate drains are required in the vent when using a
condensate tee.
• The condensate drain fitting must be plumbed to
a sanitary drain for liquid condensate disposal.
Condensate drain is plumbed with 3/8" (1 cm) inside
diameter flexible tubing.
Figure 4.
• Refer to "General Instruction For Seasonal Startup
and Maintenance", in this manual for maintenance
recommendations and schedule.

Flexible Tubing Condensate Drain Installation:
• Install tee with run outlet in vent and close to appliance.
• Install condensate drain in down outlet with high
temperature adhesive.
Figure 4.
• Connect condensate drain outlet to commercially
available flexible tubing (minimum length 40" (102
cm)).
• Below drain outlet, make 6" (15.2 cm) diameter loop in
3/8" (1 cm) ID tubing, or 9" (22.9 cm) diameter loop in
5/8" (1.6 cm) ID tubing. Secure loop with plastic cable
tie. Run other end of flexible tubing to sanitary drain
(Use condensate pump if necessary).
• Fill loop with water before firing boiler.
