Lennox Hearth T300P Care And Operation, Combustion Voltage Trim Steps, Fuel Delivery Rate

CARE AND OPERATION

Combustion Voltage Trim Steps:

1.Push button “twice” for access voltage calibration mode.

2.Identify the current calibration setting indicated by one YELLOW LED bar.

3.Push the “HEAT” control button to adjust setting UP. Each push raises the YELLOW LED bar & increases voltage 5%.

4.Push the “BLOWER” control button to adjust setting DOWN. Each push lowers YELLOW LED bar decreas- ing voltage 5%.

5.Push the calibration button once to lock in selected results.

Fuel Delivery Rate

The feed rate switch manages the fuel delivery rate by controlling the amount of time the auger motor will run as follows:

Feed	Auger Motor	* Lb.’s per	♦ Approxi-	Burn
Rate	ON / OFF	hour fuel	mate	Time
Setting	Time (sec-	delivery	BTU per	(hours)
	onds)		hour
			fuel de-
			livery
Low =	1 on / 5.00	1.5 Lb.’s /	13,000	34
	off	hr.	BTU / hr
Med.=	1 on / 3.30	2.5 Lb.’s /	21,000	20
	off	hr.	BTU / hr
High =	1 on / 1.60	3.8 Lb.’s /	32,000	14
	off	hr.	BTU / hr

*Feed rates are approximations only. Actual feed rate will vary depending on size, quality and length of fuel used and variations in line voltage.

♦Estimated heat input based on fuel value of 8400 BTU per lb. of fuel.

Your pellet stove can be operated in either manual or automatic mode. The manual mode is used when op- erating without a thermostat. The automatic mode is used when utilizing a wall thermostat. When utilizing the thermostat capability the burn time can be extended dramatically depending on thermostat setting. Note: It is normal for some ash to build up on the inner glass sur- face at the lower burn settings.

Initial Start-Up / Empty Hopper or Feed Tube: During an initial start-up, or in the case where the hop- per has run out of fuel, it will be necessary to prime the auger feed system. The control board is set to deliver fuel for approximately 2 1/2 minutes during start-up, which, with a fully primed auger tube, will provide the appropriate amount of fuel for ignition.

When first starting your pellet stove, it will be necessary to prime the auger tube. To prime the auger tube you need to first fill the hopper with pellets, and press the ON button on the control board. Wait approximately 2 1/2 minutes and turn the control OFF and then back ON again. Wait an additional 2 1/2 minutes (if necessary) and continue this process until fuel begins to fall into the UltraGrate. Remember, different brand fuels feed at different rates.

Once fuel starts to enter the UltraGrate, turn the stove OFF and then back ON. The auger tube should now be primed and the stove should deliver enough fuel for proper ignition. It may be necessary to follow these pro- cedures in the event that the hopper runs completely out of fuel.
