Raise the assembled stack and rain cap assembly (1) and position it over the tent collar assembly (2).
Lower the stack assembly (1) down into the tent collar opening (2) and into the stack adapter (3) on the
top of the heater.
Ensure that the stack and rain cap assembly (1) is reasonably secure and enter the shelter. Inspect the
connection between stack section “1” (4) and the stack adapter (3) on the top of the heater. Be sure that
stack section “1” is securely installed in the stack adapter (3).
WARNING!
Fire Danger
It is important to stake the exhaust stack securely since this will keep the exhaust stack
vertical and seated firmly within the stack adapter with a downward force. This also
stabilizes the heater and helps prevent it from being knocked over if bumped by
equipment or people inside the shelter. Secure staking assists in holding the shelter roof
and sides in position during windy conditions. If the guy lines are improperly spaced
and/or loose, the shelter roof and sides can flap during snowy, windy conditions. If the
shelter itself is not taut, the roof and side walls can flap, getting quite close to the heater,
creating a fire danger.
Outside the shelter, secure each of the three guy lines (1) to the”D” rings (2) on the tent stake straps (3)
with a double overhand knot. Pull each guy line taut but ensure that the stack assembly (4) remains
vertical. Do not pull the guy line so tight that the stack assembly begins to tip.
While standing on the side of the tent near the stack assembly, attach the first guy line to the “D” ring on
the left tent stake strap (5).
Attach the second guy line to the “D” ring on the right tent stake strap (6).
The third guy line (7) extends over the top of the shelter and is secured to the stake strap (8) located
nearest shelter door.
