AVIS
Les instructions d'installation du système

horizontales doivent être supportées pour prévenir
le fléchissement. Les méthodes et les intervalles
de support doivent être spécifiés. Les instructions
doivent aussi indiquer les renseignements suivants:
les chaudières de catégories I, II et IV doivent
présenter des tronçons horizontaux dont la pente
montante est d'au moins ¼ po par pied (21 mm/m)

catégories II et IV doivent être installées de façon à
empêcher l'accumulation de condensat;
et si nécessaire, les chaudières de catégories II et IV

The Mascot ST is standard as a Natural Gas Water
Heater and must be converted if propane is the desired
gas, unless specifically manufactured for propane.
Adequate drainage
• The appliance should be installed not to damage
the adjacent area. If such locations cannot be
avoided, it is recommended that a suitable drain
pan, adequately drained, be installed under the
appliance. The pan must not block combustion air
flow.
Connecting the Water Supply
• To conserve water and energy, insulate all water
piping—especially the hot and recirculation water
lines. Never cover the drain or pressure relief valve.
Having a backflow preventer in the cold water
supply line means that it prevent from thermal
expansion backflow. Contact the water supplier or
local plumbing inspector for information about how
to control this situation. If overheating occurs or
the gas supply fails to shut off, turn off the manual
gas valve.
This installation must conform with below section
• “Air for Combustion and Ventilation” of the
National Fuel Gas Code, ANSI Z224.1/NFPA 54,
or Sections 8.2, 8.3 or 8.4 of Natural Gas and
Propane Installation Code, CAN/CSA B149.1, or
applicable provisions of the local building codes.
