(b) If built of a single thickness of brick or of cement blocks, it shall be lined throughout its entire length
with fire clay lining, having not less than three-fourths inch (3/4") thickness. Flue lining is to be laid in
mortar and made airtight. If the chimney is of the prefabricated type, it must be an approved class "A"
chimney or type "L" Vent for interior.
(c) The furnace flue must have no other openings for attaching any fireplace, stove, range, gas or
ventilating connection unless the equipment is appropriately certified.
(d) If it is necessary to offset the flue, it must be done in such a manner as not to reduce the gross cross-
sectional area or create a ledge or obstruction, where loose material may lodge.
(e) Flue pipe connections must be secured with metal screws.
CAUTION: Oil-fired appliances shall be connected to flues or vents having sufficient draft at all
times to ensure safe and proper operation of the appliance.
BAROMETRIC DRAFT REGULATOR
A Listed/Certified draft regulator must be installed between the appliance and the chimney, within easy
reach for adjustment and free from obstruction. Use larger or multiple draft regulators for chimneys with
strong draft. Follow the manufacturer's instructions located with the draft regulator for proper installation.
BLOCKED VENT SWITCH
The WMO-1 blocked vent control is required on Newmac oil-fired and combination furnaces or boilers
installed in Canada. The WMO-1 switch must be installed on the chimney vent pipe for Newmac oil fired
furnaces and boilers; and installed on the burner plate for Newmac combination wood/oil or coal/oil fired
furnaces. Do not use the WMO-1 Blocked Vent Switch with the Newmac Sealed Vent System (SVS).
Refer to the Newmac and Field Controls Instructions enclosed in the WMO-1 package.
