Questions people ask us

What else do I need to order?

A facade. Choose the Vista inside-fit facade or one of Astria's Designer overlap-fit facades. Liners, a blower and remotes are optional.

Which ignition does each model use?

The 40 inch GEMINI40DMP-C uses millivolt ignition and burns propane. The 35 inch GEMINI35DEN uses electronic ignition and burns natural gas.

Can I vent it out the top or the back?

Either. The Gemini has a combination top or rear flue and uses IHP SV 4-1/2 by 7-1/2 inch direct vent pipe.

What are the ratings for each model?

GEMINI35DEN is an earlier production number of the Gemini 35. Ask us for the manual and the rated input of the exact model you are ordering before you frame for it.
