Fig. 5: Minimum Clearances from Combustible

Surfaces

Venting not shown for clarity. Boiler must be vented per

instructions in this manual

Combustion and Ventilation Air

This unit must be supplied with sufficient quantities of

non-contaminated air to support proper combustion

and equipment ventilation. Combustion air can be sup-

plied via conventional means where combustion air is

drawn from the area immediately surrounding the boil-

er, or via direct vent, where combustion air is drawn

directly from outside. All installations must comply with

the requirements of the NFGC (U.S.) or B149

(Canada), and all local codes.

CAUTION:

Combustion air must not be

contaminated by corrosive chemical fumes which

can damage the boiler and void the warranty. (See

the Appendix.)

NOTE:

It is recommended that the intake vent be

insulated in cold climates to minimize sweating.
