I consult to most all warm air furnace OEMs. The best answer is it lights the first time, every time. There are of course things that can prevent that...low gas pressure switches, low air pressure switches, limits not being made (door switch, air switch, fan speed proving, condensate switches, etc.). That being said...EVERYTHING good...GAS supply...AIR ...

You need to read through your owners manual. Set up procedures should tell you everything you need to know.

My furnace would ignite the pilot and energize the induction motor but the main burner valve would not open. At first I suspected a bad coil on the vale selonoid but continuity check indicated it was good. Then traced around with my meter and got to the pressure switch. It was not switching when the induction fan ran. I removed the tube from the furnace and ...

If you check the dryer installation instructions, you likely will not find any specifications for venting thru the roof. It is generally not recommended. I know my dryer blows a decent amount of lint out the vent. I can't imagine the dryer being able to push the lint out of a 30 foot chimney. I would vent it with rigid duct thru the closest wall.

Piping run concealed in finished spaces has to be installed through the joists and protected from physical damage. Or be run in black or galvanized steel. Or you could box the pipe run and shield it. Also, a flexible appliance connector has a length limit of 6 feet. Code quotes are from the 2012 IRC SECTION G2415 (404) PIPING SYSTEM INSTALLATION ...

If the valve handle is any indication for what its' function may be, than there is a very likely chance that it is a shut-off valve for: A. water supply (for flat above?) or B. sprinkler system (not likely). The valve type is either a "gate" or a "globe". Either of them are designed to control water (liquid or vapor) flow. Additionally both valve's have a ...

It sounds like you fill valve is not properly set, or has failed. Do not run the furnace until you are sure the system (boiler shell, circulating pipes, and radiators) are completely filled with water. If the water level in the boiler gets too low the system could be damaged. Boilers usually have a fuse plug that limits the damage if the water level fails, ...

This picture shows a typical gas-fired, hot water furnace system: The black thing in the center is the recirculator pump. When the furnace runs that recirculator is supposed to run. If you touch it or put your ear to it, you should detect it running. If it is making no noise, or is buzzing, then it needs to be replaced.

After cleaning the flame sensor, checking ground wire, checking exhaust for cracks or blockage and the board connection. We found that the hanger on the exhaust pipe was hung poorly and causing pipe to droop down which made it hold condensation that ran back into unit which shut the furnace down.

Pull out the bottom drawer and make sure that the wire is still connected to the igniter. That was the problem with mine. Reconnected and now everything works fine.

Check the manufacturer's installation instructions for the range, to determine the electrical requirements. A gas range typically only requires a 15 or 20 ampere 120 volt receptacle. I'm not familiar with Canadian electrical code, but I can't see why a 50 ampere circuit would be required for a gas range. If you were installing an electric range, a 120/240 ...
