Check the diagrams thoroughly before starting installation to avoid errors and minimize time and materials cost. If the system is to be filled with water for testing or other purposes during cold weather and before actual operation, care must be taken to prevent a downdraft entering the boiler or freezing air from contacting the system. Failure to do so may cause the water in the system to freeze with resulting damage to the system. Damage due to freezing is not covered by the warranty. This equ

Next, turn on all other fuel burning appliances within the same room so they will operate at their full input. Repeat step C above, checking the draft on each appliance. FIGURE 9 SAFETY RELIEF VALVES Your local code authority may have other specific relief valve requirements not covered below. WARNING THE PURPOSE OF A SAFETY RELIEF VALVE IS TO AVOID EXCESSIVE PRESSURE OR TEMPERATURE INTO THE STEAM RANGE WHICH MAY CAUSE SCALDING AT FIXTURES, TANK EXPLOSION, SYSTEM OR BOILER DAMAGE. TO AVOID SCALD

The minimum distance from adjacent public walkways, adjacent buildings, openable windows and building openings shall not be less than those values specified in the National Fuel Gas Code, ANSI Z223.1 and/or CAN/CSA B149.1-00, Installation Codes; Stack or chimney must be a minimum height of 12" (305mm) above the annual snow

This is not a warranty failure. An expansion tank or a similar device may be required in the inlet supply line between the appliance and the meter or valve to compensate for the thermal expansion of water under supply pressure, see figure 1. An air separator as shown in the piping diagrams is recommended especially for modern commercial hydronic systems. 5. VENT VALVES It is recommended that automatic, loose key or screwdriver type vent valves be installed at each convector or radiator. 6. MANIF

A hot water boiler installed above radiation level or as required by the authority having jurisdiction, must be provided with a low water cutoff device at the time of boiler installation.
