I've just run into a bad expansion noise in a multiunit condo tower. We sold Infinities for all the units (~50), and the builder used their own sub to install them. We got a call for the 1-year...

You can find the manual on the Avalon website

I agree. If you have a RCT-MLT installed, or any other control with electronic adjustment of manifold pressure, the first step is to check manifiold pressure with a manometer. When the solenoid was...

Late to the party. Our shop sells almost exclusively IPI systems from mfg's that offer them. As far as I know, H&G doesn't offer inserts in IPI. I'm a fan of the system, even if it does give up...

SP - turn out one of my other meters, an ExTech, will measure uAmps. I agree, doesn't seem to be the issue here, but I've been playing around on other units to get familiar, kind of a fun gadget.

Thanks for the good ideas and questions, everybody. Great info, HM.

Sorry to take so much time responding. I think I got it, though. I was barking up the wrong tree, though. The last tech...

Sorry HM, didn't click through to the 2nd screen. It's possible it's a spark issue, but honestly I'm not sure how to diagnose that(besides visually) short throwing parts at it.

The spark looked...

Has anybody ever tried pulling a partial vacuum in DV pipe with a shop vac and measuring the negative pressure inside the vent with a manometer to identify breaks or faults in the venting?

I have...

That should be pretty straightforward for the tech to pin down. With the wiring diagram for the insert, the they should be able to trace the blower wiring and find the fault.

Thanks for the input, everybody.

SP- I hate to admit it, but I've never done that kind of test on rectifier current. I use a Fluke 111 for most of my work, and I know that won't read microamps....

I've seen that before, too. A lot of times it seems to help to polish the sensor rod and ground strap (if present) with fine sandpaper. These SL's, though, had a delay before the pilot would light,...

Yeah, I've seen quite a few TP's and several TC's tht failed only under load, and have to be tested into a load to see the fault on a meter.

To save time, I made a little 2ohm shunt resistor on...

Hearth-Incoming pressure is 5.94, drops to 5.15 under load. I didn't check the pilot orifice, but from loooking at the pilot flame, it's definitely not an LP orifice, and the pilot looks strong. If...

JTP-The delay is only from a cold start, and the spark is nice and strong. I haven't seen any issue with pilot stability of intermitent operation, just the initial cold delay.

SP- I've seen some...

Hi Guys,

Just wanted to get some other opinions on this. I had a wty. call yesterday for 2 identical SL-750 TRS-IPI-E's that we installed several months ago. Cust. complained, "There's a 10-12...

I'm not sure I follow. This is a damper cap, right? Pull a cable inside the fireplace and it seals at the top, that kind of thing?

When you say condensation on the door, do you mean a glass...

I think it's going to get worse before it gets better, as far as servicability goes. With more interest lately in clean-face units and alternate layouts, valves are getting kind of tricky to get to...

I agree. I've found that typically, unless the bulb of a TC has burst, the TC is not the problem. Weak or drifting pilot is far more common, IMHO

TP's are the same way. Most of the time it's...
