Recently purchased a Glow Boy shop pellet stove. I cant figure out how to make it burn hot. I can get it up to 275* out the blower and thats it. I have an Avalo Astoria and I can get up to 550* out of it with the same pellets.
The glow Boy has a 22' - 4" exhaust 90ed on the back and then straight up. I thought maybee the heat was being sucked up the stack seeing that its 22' long, so I restricted the fresh air intake temperairly to see if a change, no change. I adjusted the high setting on the pellet feed to run at real hot. Yes more pellets make a bigger flame but still 275* reguardless of the blower motor setting. With the blower setting on the lowest and the pettet rate fast (faster than I like) still only 275*. Whats going on????? Any ideas.
The Astoria kicks out 3 X the heat with less pellets.
The convection blower CFM has alot to do with how hot the stove can or wont get. If the Glowboy has a larger CFM blower or the blower is running at a higher speed. The convection air will be less, But it will be moving more air around the given area. Also the heat exchanger effiency has some to do with how much heat the stove extracts and how much goes out the ventpipe.
Another thing is the actual amount of fuel being supplied to the burn pot. Max on the Glowboy is 5.5 LBS/HR est, and the Astoria approx the same. But there are variables that apply. It will depend on which stove feeds the most volume of fuel to the burnpot.
Hi Jay
I just picked up a Pelpro Bay Window similar to the Glow Boy. My Avalon Astoria does put out alot of good heat. On high (Setting 6 - 5.5 lbs per hour) I get approx 600 Degrees F with the 165 CFM convection blower. The Glow Boy I just picked up has an enormous 265 CFM blower with the highest heat setting 4 at 5.0 lbs per hour!! However I will try it with the Temp probe when I get it setup
See my Pelpro/Glow boy specs

It will take time to get mine going but to help with resolving this issue the trim pot for the Fan Speed on the glow boy control panel can be adjusted down to decrease the fan speed per the instructions in the Pelpro or Glow boy manual as copied here below. Also see pic below
TRIM POTS (Fine Tune Adjustments)– Factory Settings
The COMBUSTION FAN (FAN), HI (4) and LO (1) FEED RATE trim pots have been preset at the
factory, but may need to be adjusted onsite after your installation is complete. Due to different
installation setups, length and size of venting, and pellet fuel quality, the preset from the factory will
not always be correct. These settings will accommodate virtually all wood pellet fuels.
FUEL FEED rates at the Lowest (number 1) and highest (number 4) settings can be adjusted by
adjusting the fine tune trim pots located on the control panel. To raise fuel feed turn trim pot
counter clockwise and to lower turn clockwise. To assist in knowing what the change is you
should note the amount of time the light on the AUGER CYCLE LED stays OFF. (Note: The light
stays on when ever the fuel feed motor, AUGER CYCLE, is running). Lengthening the time this
LED stays OFF lowers the fuel feed and shortening the off-time increases the fuel feed.
COMBUSTION FAN SPEED (FAN)
In a few instances because of prevailing conditions pertinent to your specific installation, or even
different batches of pellet fuel, the COMBUSTION FAN SPEED may be adjusted to raise or lower
the amount of air moving through the grate for the cleanest burn. The FAN speed can be adjusted
by adjusting the FAN trim pot COUNTER CLOCKWISE to INCREASE the speed and CLOCKWISE to DECREASE the speed
of the combustion fan.
Note: If you attempt to adjust the Fuel Feed Trim Pots, use a small precision screwdriver.
The Trim Pots do not make a full rotation.
If using a metal screwdriver, be gentle as the plastic trim pot slot can be damaged or stripped.
