REFER TO FIG. 3A PG. 21 FOR FURTHER DETAILS.
1)
Never vent into a walkway or patio area, or any alley, or otherwise public area less than 7' from the ground.
2)
never install a heat saver or similar product to capture waste heat from exhaust.

Always have a vent location at least 1' above maximum snow level.
4)
Always have vent 1' above ground level, away from shrubs and bushes.
5)
Always be at least 2' horizontally from doors or windows. (36" for Canadian installations. Refer to Fig. 3A pg. 21.)

11) The vent intake and exhaust must be properly cleaned and glued, for pressure tight joints. Several methods for
venting the Super-E can be found on pages 22 and 23. Use the following layout as a guideline; certain site
conditions such as multiple roof lines/pitches may require venting modifications – consult factory. The air inlet must
be a minimum of 1' vertically above the maximum snow level of 24", whichever is greater. The air inlet must also be a
minimum of 10' horizontally from the roof, and terminated with a tee. The exhaust must be minimum of 24" above the
air inlet opening, and terminated with a coupling. It is very important that there are no other vents, chimneys, or air
inlets in any direction for at least 4'. Please refer to typical venting on pages 22 and 23. ALL VENTING MUST BE
PROPERLY SUPPORTED, AS THE VOYAGER IS NOT INTENDED TO SUPPORT ANY VENTING
WHATSOEVER. All piping, glue, solvents, cleaners, fittings, and components, must conform to ASTM (American
Society for Testing and Materials), and ANSI (American National Standard Institute).
12) It is recommended that you use one of the mentioned vent kits specifically for Super-E installations; either
KGAVT0501CVT (2 in.) or KGAVT0601CVT (3 in.) or the V1000.
