Hello, I have a Bounder RV with a year old Suburban SF-35Q furnace ... about a weeks run time on it. A few weeks ago I replaced the propane regulator. At the time, I noticed the unit was trip...

There are 2 appliances that have built in regulators on the system.
1. The Oven/Range has a separate regulator that drops the 11.5 to 10 as that is the operating pressure of this appliance
2. I have NEVER in 40 years had to worry about what a Furnace valve /reg may do. ALL I do is verify I have 11.5 minimum to the LP furnace. Since Suburban states it has its own reg that drops to 10 to 10.5, we will believe this. This is the 2nd appliance then.
3. Where are you taking the LP pressure on your manometer? And is this the same place when you have the furnace running?
4. How hard is it? Well, if you are not trained to work on RV systems and furnaces, then it may seem difficult. You seem to have an unusual problem and this is where years of experience can come in.
5. You still not have posted 2 answers. 1. How hot does the furnace casing get?(IR thermometer) 2. How long does it take before it trips the hi limit? also, how long before it resets?
6. Are you positive you have the correct Hi limit for your newer model furnace? You stated you replaced it, but do you have the correct part number and temp range? Doug
