need to buy extra accessories for venting options. The ProMax

features that come standard and make the installation easy
& convenient. This improved design on the standard input DV
models have Energy Factors that exceed the current NAECA
minimum Energy Efficiency requirements and is superior to
all competitors in the market.
Ease of installation is standard
n Easy to handle flex-vent material, that expands to a distance of 80˝
from the outside wall with no electrical power needed. This feature
comes in a factory supplied kit. Other brands have kits, that must be
purchased separately to extend their vent to this distance.
n Horizontal through-the-wall termination only. All vent pipe &
termination cap, ship with the heater.
n Our contour formed air intake snorkel makes for a smaller overall
footprint allowing for installation in tighter applications, saving
valuable space.

the home, eliminating problems caused by insufficient indoor
ventilation. All units are FVIR compliant.
