The Dynapack unit uses outside air for combustion and vents the exhaust products
directly outside. The Dynapack unit cannot be vented with other appliances. The
venting system of the Dynapack unit cannot be modified or adjusted in any manner
other than what is specified in these instructions.
The installation must be planned before hand so that the unit exhaust vent location
complies with local or national codes in regards to distances between the unit vent
and doors, operable windows, side walks, balconies, and patios. See the National
Fuel Gas Code Z223.1 for the USA or Installation Code CANI-B149 for Canada.
See figure 11 at the end of this chapter.
The venting system for the Dynapack 90% condensing furnace must be completed
in the field using 1 1/2 inch PVC schedule 40 DWV pipe. The vent pipe will be
straight for the full unit width wall sleeves. See Figure 7 for the typical full unit width
vent pipe installation. The vent pipe must terminate approximately two inches
outside the exterior grille.

Before installing and securing the unit to the wall sleeve, make sure that the
proper grille kit is installed. Due to the temperatures of the combustion products
released from the gas vent, DynaPack gas package units require the use of an
aluminum grille kit (see the Accessories chapter).
1. Double check the installation of the wall sleeve to make sure it is securely
attached to the wall opening. Inspect the wall sleeve drain for proper
installation if an inside drain is being used.
2. Examine the gaskets on the wall sleeve to make sure there is a continuous
seal between the wall sleeve and the unit.
3. Place DynaPack unit onto the wall sleeve. Lift the unit 3/4" and place
over the wall sleeve base (see Figure 8). A PALLET JACK works well for
this. Temporarily block the unit up and install front leveling bracket (see
Figure 8). Adjust leveling legs to level.
4. Use the two retaining straps to secure the unit to the wall sleeve (see
Figure 8). Verify that the gaskets of the wall sleeve make a complete seal
to the unit paying particular attention to top and bottom corners of the unit
to sleeve seal. Caulk if needed.
