VFC 15-150 - VFC 45-225 MODULATING GAS BOILERS
1.5.1.1 WITH SCHEDULE 40 PLASTIC VENTING SYSTEMS
(E.G. ULC-S636 CPVC)
A condensate trap must be installed near the base of the boiler as shown in Figures
14 or 15.ThetrapisformedusingPVCpipe,elbowsandthreadedunionttings.
NOTE: for CPVC vent systems, the connecting tee and bushing should be
formed using CPVC, transitioning to PVC in the wetted section of the trap, where
non-ULC-S636materialsareallowedasthissectionisnotincontactwithue
products. The trap must be installed as follows:
• For the 15-150 model, must be 7” min in height (see Figure 14); with the
conventional vent kit parts supplied with the boiler, approximately 15”
clearance below the boiler is required. For the 45-225 model, the trap shall
have an effective minimum depth of 16” (up to 24” below may be required;
this can be achieved using a conventional drop as shown below or a ball trap
assembly of similar properties).
• Use the supplied vent kit parts to establish the trap in the location shown
below. Do not place the drain connection tee directly at the base of the boiler.
