Sidewall Venting
The Peerless WV-DV is designed and built to be vented through a side wall of a building using a
stainless steel concentric vent terminal (4 inch diameter tube inside an 8 inch diameter tube).
Exhaust gases from combustion contain water vapor. During the cooler months of the year, this
water vapor will condense into a visible vapor plume. This water vapor may condense on any
surface near the vent terminal. Care must be taken not to locate the vent terminal where the exhaust
gas, vapor plume and condensation could cause a hazard or a nuisance. Do not locate terminal
under a deck, for instance, as it may create a coating of ice on the deck during the winter months,
as well as shorten the life of the deck materials. Refer to Chapter 4 in this manual for specific
terminal location requirements. Condensate from a side wall vent terminal may also cause paint on
surrounding surfaces to crack and peel. If the boiler is used to heat potable (tap) water, the boiler
will cycle year round. The effects of hot exhaust gases and odors must be taken into consideration
during summer months.
Side wall vented, oil fired appliances may cause soot staining on wall surfaces surrounding their
terminals. To reduce the potential for staining, the boiler must be serviced annually. Soot and scale
must be completely removed from the combustion chamber and cast iron heat exchanger flueways.
See Chapter 7 in this manual. The oil burner must be completely serviced and set up according to
the specifications shown in Chapter 5 of this manual.
