Section F- Catalyst Monitoring (continued..)

Step 1- Light stove in accordance with instructions in section ‘E’.

Step 2- With smoke routed in the by-pass mode, go outside and observe the emissions leaving the chimney.

Step 3- Push in the by-pass mechanism and again observe the emissions leaving the chimney.

Significantly more smoke should be seen when the exhaust is not routed through the combustor (by-pass mode). Be careful not to confuse smoke with steam from wet wood.

Section H- Operation and Maintenance

*RECOMMENDATIONS FOR BUILDING AND MAINTAINING A FIRE:

CAUTION: HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN BURNS

1.Pull by-pass control out to open.

2.Start with tinder and small kindling. When starting a fire, stack the wood in a ‘criss-cross’ arrangement so as to allow the fuel plenty of air. Place smaller chunks of wood on up to larger chunks until desired fire is reached.

3.Open air vent controls. Crack door open 1/2” to help establish start-up fire. Close after start up is achieved. The door will need to remain cracked open approximately 25-30 minutes (close door 10 minutes after you close by-pass).

4.Leave by-pass and air controls fully open until a medium to high burn rate is achieved (about 15-20 minutes). After start-up, push by-pass control in. Adjust the air controls at bottom to achieve the desired heat output. See
