It’s forced air. Does have a clean filter and yes common to get into the 20s.

I need to figure out how to measure water temp inside.

I use one of those inferred temperature guns point it at the inlet of the HE then check the outlet.

I’ll take a pic, I don’t even know what the HE looks like.

From page 24 owners manual crown royal outdoor boilers

"FILLING THE WATER JACKET
Your outdoor furnace has a vent pipe that protrudes through the roof and is behind the chimney. By placing a garden hose in this pipe you can fill your furnace to the proper water level. Because this furnace is an open-to-atmosphere system, it is normal that water will have to be added annually. Depending on circumstances, 5 or 10 gallons is not unusual. To make this procedure more convenient, a boiler drain valve (tap, faucet) can be installed into the return furnace line allowing you to connect a double female (automatic washing machine hose) between it and your domestic supply line.
On your initial filling of your furnace make sure to inspect all connections in your system for leaks. In your system a bleeder valve should have been installed at the highest point. This will allow you to remove any air from the system. CAUTION - do not fire furnace until it is filled with water.
Allow furnace to run for two days and check water levels and fittings for leaks. If all is okay, you now should add the manufacturer’s recommended water treatment"

I have the same "open vent system" which means it is non-pressurized. Mine has a vent cap with a short copper tube running through the cap to allow for venting. The plastic cap itself prevents the condensation/evaporation cycle of the stoves water through the top vent. Maybe his is missing?

That's great info .. we got that figured out but there's more issues he needs to fix . He had the pump sucking the water thru the 2 exchangers he has .and now he will re plumb it and get pump pushing water thru the plate exchanger and air exchanger . I don't know how it even worked like that . It was only the equivalent of a 007 taco pulling 75 feet and thru 2 exchangers . I think boiler water weight was only thing feeding the exchangers. Ya he will be a busy guy.

O oooo and burned that pump up also .
