What is Type L vent?
Type L vents are designed for venting approved oil-fired and natural-gas appliances that produce draft hood flue gasses that do not exceed a temperature of 570º F (299º C), or 926º F (299º C) for 10 minutes in an over-fire situation. The minimum clearance from combustible materials is generally 3 inches.

What is the maximum temperature of flue products that a Type L vent is approved for?
570 °F
Additionally, Secure Seal (Models SSD/SSID up to 24”) is listed to UL 641 and ULC S609 as a Type L Vent for venting approved oil or gas appliances producing draft hood flue gases not exceeding a temperature of 570 °F (299 °C).
What is Category II venting?
Gas appliances are divided into four venting categories based on vent operating pressure and whether they are condensing or non-condensing. Category I is negative pressure, non-condensing. Category II is negative pressure, condensing. Category III is positive pressure, non-condensing.
Can you vent oil and gas in same chimney?

Do I need a boiler flue guard?
∎ T he Gas Safe Register guidance on the Gas Safety Regulations states that terminal guards are required to any gas flue terminal within 2m from finished ground level. Guards should be fitted over all flue terminals less than 2m above finished ground level which people can come into contact with.
What’s the difference between open flue and room sealed?
Plant rooms will require less ventilation than open flue systems, and with reduced air flow, warmer room temperatures are possible – a useful point when designing tighter buildings. Room sealed appliances reduce the risk of flue gases spilling back into the plantroom due to poor flue operating conditions.
Do I need a chimney liner for oil boiler?
An oil furnace needs a chimney liner. The purpose of any chimney liner, or flue, is to keep the smoke, fumes and toxic gases from penetrating the chimney mortar and entering the living space. The fuel used in an oil furnace creates an oil mist.
Does my furnace chimney need a liner?
For optimal use and safety, a liner is needed when installing a new heating system, furnace, boiler, or water heater. Local codes and the International Fuel Gas Code require proper venting and chimney liners for flue gasses to be vented into the outdoor atmosphere.
Does an oil boiler need ventilation?
An oil boiler needs oxygen for burning fuel so a supply of air is essential. Modern oil boilers will have a balanced flue system to let in air and remove waste gases. This removes the need for any air vents around the boiler. If your oil boiler does need ventilation then the vents must have openings that don’t close.
