LIMITATION OF INSTALLATION
A water heater should not be installed in a bathroom or a bedroom, unless it is of the entouses.
(7.26.1)
SAFETY VALVE
All water heaters must be fitted with a safety valve pressure and temperature approved and include a pipe discharge complies with local plumbing code.
The exhaust pipe must have a diameter at least equal to that of the output of the device and must end at 12 inches (300 mm) on the floor. (7.26.2)
Condensing Tankless Gas Water Heater
Instantaneous water heaters installed on a combustible wall must be protected by an insulating board of 0.25 in (8 mm) or equivalent, which extends over the entire length and the entire the width of the water heater and its draft hood, unless otherwise directed by the manufacturer. (7.26.3)
BAN & RECOMMENDATION
> Do not connect the safety valve directly to a referral.
> Avoid installing a water heater in mechanical spillway near a bedroom because of the noise.
> Do not use an extension cord (extension) to connect a device or its accessories to a socket wall power.
Do not install natural draft system in a room where there would be a negative pressure.
Residential atmospheric vent natural gas
OPERATION
There are three types of evacuation of combustion gases when it comes to hot water heaters:
1. Atmospheric vent requiring a chimney on the roof. This unit is autonomous in case of power failure.
2. Direct vent and to be installed near a wall on the outside. This unit is autonomous in case of power failure.
3. Mechanical evacuation and with only very little installation constraints. This unit is not autonomous in case of power failure.
Advantages
> Recovers its heat at least two times faster than electric water heater, generating energy savings.
> Provides hot water in abundance.
> Allows for hot water even in case of electrical failure since most models are autonomous.
> Provides flexible installation with three types of evacuation.
> Moves to a yield of 90% through condensing models.
