While observing the above guidelines, install the condensate trap as follows:
Condensate Trap Installation
1. Connect the condensate trap inlet to the exhaust manifold drain connection by inserting
the drain port directly into the trap adaptor inlet, and then tightening the inlet thumbscrew,
as shown in Figure 2-6. The inlet features two integral O-rings to prevent leakage.
2. At the condensate trap outlet, install a 3/4” NPT nipple.
3. Connect a length of 1” diameter polypropylene hose to the trap outlet and secure with a
hose clamp.
4. Route the hose on the trap outlet to a nearby floor drain.
If a floor drain is not available, a condensate pump can be used to remove the condensate to
drain. The maximum condensate flow rate is 30 GPH. The condensate drain trap, associated
fittings and drain line must be removable for routine maintenance.
Use PVC, stainless steel, aluminum or polypropylene for condensate drain
piping (Figure 2-6). DO NOT use carbon or copper components.
