Questions about this product

What room size will each model handle?

323 Square Feet

Do they need electricity and will they run during an outage?

No power required. They use a standing pilot with a piezo ignitor and a mechanical control, so they keep heating with the lights out.

What clearances and mounting height do I need?

Sides 6 in. Above 24 in. From finished floor 7 in to the bottom of the heater. Rear clearance: MDV8 is 25/32 in, MDV12/MDV20 are 1-3/16 in. Use the included wall template. Keep the exterior vent cap at least 24 in from any outside intersecting wall.

What comes in the vent kit and what wall thicknesses are supported?

Vent kit includes: external air-intake tube with enamel hood, internal flue-gas tube, indoor and outdoor mounting plates, plus a wall thimble on MDV12 and MDV20, with threaded rod and adjusting nut. Approved wall thickness is 4-1/2 in to 12-5/8 in. Thicker walls aren’t supported by the manual.

Can I convert propane to natural gas, and what about high-elevation derate?

These units are not convertible. Order the model for your gas type. Above 2,000 ft, reduce input by 4 percent per 1,000 ft.
