You can see a fireplace as simply the wonderful
source of warmth and renewal that it is, but look
again.A multi-sided fireplace can also be a room
divider, a window, or a dramatic architectural element.
• In popular, exible sizes—along with a variety of models and
options—our multi-sided family is ideal for new construction,
renovations and additions alike.
• Pier, See-Through and Corner vent off either the side or top,
inspiring creative installation and design ideas.
• Each model offers a direct vent, completely sealed system
that draws air for combustion from the outdoors only and
expels any combustion by-products outside, maintaining
clean indoor air.
• Standard electric ember beds in the Pier and See-Through
provide year-round enjoyment of the replace, with or
without ame.
There’s more than one way to look at a gas fireplace.
Multi-Sided

Pier
The Pier provides three-sided viewing,
and it works perfectly as a room
divider or even the base of a bar. Finish
with Aero,Arcadia or Chateau Deluxe
front.
See-Through
The See-Through brings two rooms
together while letting you design each
side differently. Available in 32" and
36" models. Finish with your choice
of front or door options.
Corner
Put a dark, dull corner to better use.
This multi-sided model adds light and
warmth to any corner, left or right.
Finish with an Aero front.

sided fireplaces might not. Our patented
draft-assist technology combined with
its smaller size means the Gateway can
be installed virtually anywhere. Includes
top and bottom louver assembly. No
front or door required.

air from outdoors and discards all combustion by-products back outside.

gas-burning products for their most important aspects: firebox and heat
exchanger. For full warranty details, go to www.heatnglo.com.

consumption and thermogenerator wear by providing a pilot flame
only when needed. It also supplies a back-up battery system to run the
