Emergency Heat
In the event of a power outage, the DVHVAC36 unit can be run in an emergency heat mode. Simply turn the unit on by toggling the rocker switch located on the front of
|
| the electrical junction box to the |
|
| |
|
| "ON" position. This will turn on |
B15 |
| the fireplace burner in a low fire |
| condition. The unit will provide | |
|
| |
|
| heat to the room in which the |
|
| fireplace is installed. When power |
B14 |
| is restored, toggle the emergency |
|
| heat switch to the "OFF" position. |
|
| NOTE: When in the emergency |
|
| heat mode, the air circulating fan |
|
| will not operate. In order to pre- |
|
| vent overheating of the duct work, |
| B12 | the unit will periodically cycle on |
|
| and off. The length of cycles will |
|
| depend upon factors such as the |
|
| length and design of the duct- |
|
| work, interior temperature and |
LG310 |
| venting arrangements. |
|
|
|
NOTE: When the electricity is off, the thermostat will not operate
the unit. The unit must be controlled manually through the emergency heat switch located on the front of the electrical junction box.
Flame Characteristics
It is important to periodically perform a visual check of the pilot and the burner flames. Compare them to Figures 39 & 40. If any of the flames appear abnormal, contact a qualified service provider for service and adjustment.
