NOTE: Machines to be used indoors MUST be in accordance with local regulations and CSA Standards B139.
•
Make sure chimney is of suitable size. (7" minimum).
•
Make sure that there is enough air for combustion.
•
Be sure to protect against a down draft in below freezing weather.
A DOWN DRAFT CAN CAUSE THE COIL TO FREEZE, RESULTING IN EXPENSIVE DAMAGE!
CHIMNEY SIZE
•
All venting should be the same size as the stack opening (7" minimum).
•
Never use vent pipe smaller than the stack opening.
•
If total run is more than 25', use larger size chimney.
•
A 90 degree elbow is equivalent to a run of 20 feet.
•
If a horizontal run is used, make sure the flow rises at least 1/4" per foot.
COMBUSTION AIR SUPPLY
•
These hot water pressure cleaners burn No. 1 or No. 2 Fuel Oil. This means that air is required for
combustion and for ventilation.
•
The appliance installer will know how and where to place a supply air duct. Take care that this opening will
not promote drafts which could blow out the pilot light.
•
Keep the area around the machine clear so this air can get to the burner. If the wheels are removed, the
machine should be bolted to a stand 18" off the floor.
APPLIANCE IN CONFINED SPACE
•
The confined space should have two permanent openings: one near the top of the enclosure and one near
the bottom of the enclosure. Each opening shall have a free area of not less than one (1) square inch per
1000 BTU's per hour of the total input rating of all appliances within the enclosure. The openings shall have
free access to the room interior which should have adequate infiltration from the outside.
