InCanada the installation must conform to CSA Standard B139, "The installation Code for Oil BurningEquipment.

7 " In the United States, the National Fire Protection Association Standard NFPA 31 should befollowed. Check with provincial, state, or local codes concerning clearances, venting system requirementsand other regulations governing installation . Some codes may vary from the requirements set forth in ensurethe boiler is on a level foundation and above any possible dampness, a cement pad minimum clearances to combustible construction are as follows:6"Side: 6 Top: 6 Rear: 6 Front: 24"Flue Pipe: 9"Approved Floor Type: CombustibleAllow sufficient room for YOUR SAFETY: Do not store or use gasoline or flammable vapors and liquids in the vicinityof this or any other PRODUCTS OF COMBUSTIONC himneysThe required minimum flue pressure inches of water column.

8 The required minimum overfirepressure inches of water column. Locate the boiler as close to the chimney or flue as maximum draft is obtained by keeping elbows and pipe length to a minimum. Install the flue pipe witha gradual rise of at least 1/4" per foot from the boiler to the flue. Do not extend the flue pipe beyond theinside wall of the chimney. Refer to Table 8 (a) and Table 8 (b) for proper sizing and Figure 19 foroptimizing chimney owner shall provide a chimney constructed to comply with the following specifications:(a) The chimney must be absolutely smoke tight throughout its entire length, and must extend at leastthree feet (3') above a flat roof or two feet above the ridges of peak roofs.

9 (b) If built of a single thickness of brick or of cement blocks, it shall be lined throughout its entire lengthwith fire clay lining, having not less than three-fourths inch (3/4") thickness. Flue lining is to be laid inmortar and made air tight. If the chimney is of the prefabricated type, it must be an approved class "A"chimney or type "L" Vent for interior.(c) The boiler flue must haveno other openings for attaching any fireplace, stove, range, gas or ventilatingconnection 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.

10 (e) Flue pipe connections must be secured with metal : Oil-fired appliances shall be connected to flues or vents having sufficient draft at alltimes to ensure safeand proper operation of the Draft RegulatorThe Listed/Certified draft regulator must be installed between the appliance and the chimney, within easyreach for adjustment and free from obstruction. Use larger or multiple draft regulators for chimneys withstrong draft. Follow the draft regulator manufacturer's instructions for proper VentingConsult installation codes for requirements and approvals governing power venters and draft the instructions supplied with them for proper Sealed Vent SystemConsult the GENERAL INSTRUCTIONS of this MANUAL for approved burners.
