QUESTIONS AND ANSWERS

FPS MODELS

QWhat is the CFM of the blower?

A.Maximum of 60 CFM

QWill the blower move more air through the unit than conventional venting and thereby cause less heat to be transferred into the water?

A.No. The unit has been tested to the DOE test methods for recovery efficiency using the minimum and maximum amount of vent piping with the resulting GPH rates as shown on the spec sheet. The baffle and air intakes of the heater still regulate chamber air flow.

Q.Can this unit be vented to a chimney?

A.No. The unit may have condensing flue gases which would attack mortar or standard vent piping.

QCan I vent the FPS unit vertically?

A.The Series 216 & 217 are sidewall venting only.

The Series 220 and higher can be vented either vertically or horizontally.

0, Will a snow/riser kit be available?

A.A snow riser kit can be constructed in the field in parts of the country where applicable. The venting should be terminated a minimum of 12 inches above expected snowfall

accumulations.

Avoid installations where snow drifting or prevailing wind conditions will interfere with the venting of the heater. Installation of a condensate tee is necessary to prevent condensation from reaching the blower housing.
