It comes with a ceramic fiber log set and a factory-installed blower.
Model numbers DVC28IN31N and DVC28IN31P are millivolt, with a standing pilot that needs no house power; DVC28IN71N and DVC28IN71P are intermittent pilot, with battery backup. N is natural gas and P is propane. A surround is required, and the insert is approved for bedrooms in the US and Canada.

The Innsbrook Large: A Direct Vent Gas Insert for Your Wood-Burning Fireplace
The insert is 34 3/16" wide at the front (21 3/4" at the rear), 23 1/2" high and 16 5/8" deep. It fits a listed wood-burning masonry or factory-built fireplace with an opening of at least 23 1/2" high, 34 1/4" wide at the front, 22" at the rear and 16 5/8" deep, and a flue at least 8" in diameter.
The two liners, one for intake and one for exhaust, run up the existing chimney 10 ft to 35 ft to a vertical termination cap. The original non-combustible hearth stays, at least 16" deep in front, and the blower plugs into a 120V outlet in the old firebox or on the hearth.

Installation Requirements
-
Fireplace: installs in a listed wood-burning masonry or factory-built fireplace with a minimum opening of 23 1/2" H x 34 1/4" front width x 22" rear width x 16 5/8" deep, and a flue at least 8" in diameter. The damper may need to be removed. A factory-built fireplace that has been modified for the insert cannot go back to burning wood.
-
Hearth: the original non-combustible hearth must stay, extending the width of the fireplace and at least 16" in front; wood flooring, vinyl or carpet may not be directly in front of the insert.
-
Clearances: at least 8" from the edge of the barrier screen frame to a perpendicular combustible side wall; 1/4" to combustible material under the insert. Nothing combustible may go behind the surround or the insert.
-
Mantel and trim: a combustible mantel or trim must meet the mantel and trim chart in the installation manual.
-
Venting: two 3" flexible aluminum or stainless liners (intake and exhaust) run up the existing chimney to a vertical termination cap, from 10 ft up to 35 ft. Horizontal termination is not allowed, and the cap must sit in open air, not under a cap shared with other flues.
-
Power: a 120V cord for the blower is included; plug it into an outlet in the old firebox or on the hearth, with GFCI protection where codes require.
-
Installation: must be installed by a qualified installer per the installation manual and local codes. In Massachusetts the installation must be done by a licensed plumber or gas fitter.
Make It Yours: Surround, Front and Liner
The steel surrounds come in black or bronze with 3" sides and a 6" top, 6" sides and a 6" top, or 6" sides and a 9" top (28 1/4" high, 40" wide with 3" sides or 46" with 6" sides), and a matching bottom cover fills the gap when the surround stops short of the floor. The black cast iron surround (SC356BL) needs the SAK28 adaptor kit and does not take a decorative front or bottom cover, and custom 3-sided and 4-sided surrounds are available. The SH1BL shroud, 48" x 35 3/4" with a bottom panel, covers a larger fireplace opening.
With a steel surround, add the Lancaster front in black or bronze, the Horizon front or the Transom doors. Inside, choose a traditional aged brick, washed brick, black porcelain or banded brick liner. Controls run from an on/off remote (FRBC) or wall switch (FWS1) to a thermostat remote (FRBTC2), a programmable touchscreen remote (FRBTPS) and wall thermostats (the TMV reed switch or the TRW wireless). On intermittent pilot models, the variable flame remote kit (RVKN or RVKP) adds a stepper motor and thermostat remote for flame adjustment.

FAQs
Which Innsbrook is right for me?
The Innsbrook Large (DVC28IN) is the 28,500 Btu/hr direct-vent model. Every Innsbrook is a traditional gas insert with a log fire for an existing wood-burning fireplace, and every one needs a surround. The direct-vent Innsbrook Small, Medium and Large (DVC20IN, DVC26IN and DVC28IN) vent up the chimney through two 3" flexible liners, come with a ceramic fiber log set and a blower, run up to 20,500, 26,000 or 28,500 Btu/hr and are approved for bedrooms. The vent-free Innsbrook inserts need no chimney or vent and can also be built into a framed wall: the VFPC20 (20,000 Btu/hr) comes with its log set, brick liner and blower, and the VBPC28 (28,000 Btu/hr) comes with its blower and takes a log set and liner ordered separately.
Will it fit my fireplace?
It needs a listed wood-burning masonry or factory-built fireplace with an opening of at least 23 1/2" high, 34 1/4" wide at the front, 22" at the rear and 16 5/8" deep, and a flue at least 8" in diameter. The damper may need to be removed, and a factory-built fireplace modified for the insert cannot go back to burning wood.
What venting does it need?
Two 3" flexible aluminum or stainless liners, one for intake and one for exhaust, run up the existing chimney to a vertical termination cap, from 10 ft to 35 ft. Horizontal termination is not allowed, and vent pipe is ordered separately.
Can it go in a bedroom?
Yes. It may be installed in a bedroom or bed-sitting room in the US and Canada.
Can I switch it between natural gas and propane?
Yes, with the conversion kit for its control: 36400 (natural gas to propane, millivolt), 36399 (propane to natural gas, millivolt), 36727 (natural gas to propane, intermittent pilot) and 36726 (propane to natural gas, intermittent pilot).
