When two or more appliances are connected to the same vent,
(a) the appliances shall be oil- or gas-fired or designed and certified for use in conjunction with oil-fired equipment;
(b) the appliances shall be located on the same storey;
(C) the vent outlet pressure of each appliance shall be negative;
(d) each appliance shall be equipped with an individual draft control, unless otherwise certified, so as to maintain the over-fire pressure (draft) specified by the appliance manufacturer;
(e) the vent connectors of the appliances shall be connected directly to a common vent connector of adequate cross-sectional area and as close to the chimney as practicable or directly to the chimney vent with the vent connector from the smallest appliance on top. A solid-fuel-fired appliance shall be connected below (upstream of) any oil-fired appliance connection;
(f) the chimney vent shall be capable of venting the flue gas by natural draft when all appliances are firing at the same time, or a mechanical flue-gas exhauster shall be used; and
(9) notwithstanding Item (e), an oil-fired appliance may be connected to a common vent serving two or more oil-only-fired appliances, in excess of the chimney vent capacity, provided that the appliances are equipped with a means to ensure that only the number of appliances the chimney is capable of venting (as determined in accordance with Clause 52.2.4) shall operate simultaneously at any time.

When a chimney flue serving a liquid-fuelled appliance also serves a gas-fuelled appliance, the gas-fuelled
appliance vent connector shall be
(a) through a separate flue opening above the flue pipe connected to the liquid-fuelled appliance; or
(b) connected into a shop-fabricated branch fitting that is located
(i) in a dwelling unit not more than 750 mm (30 in) from the flue entrance; and (ii) in other than a dwelling unit, as close as practicable to the chimney.
When the total flue-gas temperature exceeds 400 °C (750°F), as determined in accordance with
Clause 184.108.40.206, the vent connector shall not pass through a combustible wall or partition.
When the total flue-gas temperature is 400 °C (750°F) or less, when determined in accordance with
Clause 6.2.1 .1, the vent connector may pass through combustible walls o partitions, provided that the
construction is guarded at the point of passage by one of the following means:
(a) a metal-ventilated thimble not less than 305 mm (12 in) larger in diameter than the pipe;
(b) a metal oi’ burned fire-clay thimble built in brickwork or other similar material extending not less than 203 mm (8 in) beyond all sides of the thimble; or
(C) in lieu of such protection as specified in Items (a) and (b), all combustible material in the wall or partition shall be cut away from the vent connector at a sufficient distance to provide the required clearance indicated in Table 4 and Figure 1 from such a vent connector. Any material used to close up such an oDeninci shall be noncombustible insulating material.CSA B139-09 pdf free download.
