I have a customer that is complaining of a gas smell from the exhaust of a relatively new Mastertemp 125. I'm not quite sure if it's actual gas, or just the smell of the exhaust. I don't know that my nose is sensitive enough. To me, it just smelled like exhaust. The gas pressure reads fine, it's outdoors (well ventilated). What are some other possible explanations for this. Is a gas sniffer the best option to test this out? Is it normal for some minor or minute amount of gas to always come through the exhaust?
Gas vs normal exhaust smell on mastertemp 125 heater
- Thread starter QPSUtah
- Start date
Check Stack Flue Temperature.
Check Flame Current.
Check Gas usage; it should be 125 cubic feet per hour.
Propane or Natural Gas?
Is the heater correct for the type of gas?
Heater Part Number?
Heater Manufacturing Date and Installation date?
Did the problem just start happening?

It is completely normal for those heaters, at start-up, to smell gas in the exhaust just as the flame lights. Gas is being forced into the combustion chamber by the blower and some will escape before it all lights. Afterward there can be a faint smell of gas, but if the burner is lit it is just the "stuff" (mercaptan) that is put into natural gas so that you do smell it.
