    Mr Heater Exhaust vent

    If you choose to use the flex pipe (part number 4EFC3), one end of it has the connection you need to go directly from exhaust of the heater, negating the need for part 4RV-DH. Instead of an elbow, I would personally use a tee fitting (with cap on the bottom of tee) to join the horizontal and...

    Mr Heater Exhaust vent

    You have a Selkirk brand of "B" vent piping. In order to keep from having to replace all the vent piping, you're likely stuck using Selkirk brand vent pipe, as inter-joining different brands like Duravent might be a pain in this case. Looks like you'll need Selkirk #4RV-DH from the heater...

    Generally yes. More modern thermocouple powered/pilot based devices have the safety built into the main gas valve. Older gas heaters had a separate device that the thermocouple would cut off before the gas valve.

    Hot surface ignition kit

    Not sure if you'll ever recoup the cost given winter lasts about 6 months in the Midwest. The other 6 months you can just turn the pilot fuel off and relight when needed. With that said, I have done a few conversions on similar standing pilot equipment. I would post a link to a kit, but my...

    Big Maxx ignition problems.

    It sounds like you are using LP/propane gas. Are you running it off a 20 or 50 pound stand alone cylinder?Based on what you are describing, you are either losing pressure under load/fire or have bad carryover on the burners. Leave the manometer on the gas valve outlet/manifold side and watch it...
