In brief:
- 1.6.4 Ventilation shall ensure proper operation of the gas appliance and flueing system and maintain safe ambient conditions
- 2.2.6 Where a gas appliance is installed in a room, that room shall be ventilated
- Where the total input of open flued appliance exceeds 3MJ/hr for each cubic metre of room volume, the area shall be ventilated
- Where the total input of open flued appliance does not exceed 3MJ/hr per cubic metre of room volume, the required air may be provided by adventitious openings, ie gaps around doors and windows
- to establish whether the required air is to be provided by adventitious openings or additional openings. Calculate the total input of the gas appliance or appliance in the room in MJ/hr and divide by the room volume in cubic metres
Total gas input MJ/HR
Divided by
Room Volume m3 L x W x H
X
X
= m3
= MJ per cubic metre
2.6.6.1 Natural ventilation. Two permanent openings shall be provided each with a minimum free area as calculated using:
A = FxT formula
A = Minimum free area mm square
F = Factor given in table 13
T = Total gas consumption of all gas appliances
