Jetmaster 850 Bedrock Flueless Fire Outdoor (N.T.S.)
The installation of the 850 BROFF is designed to be fitted directly into a Hebel heat cell when into a timber frame out.
For a Masonry installation where no combustibles are present within 200mm of the firebox sides or back and 600mm
above the front or top of the firebox, the masonry enclosure opening may be set up dimensionally to take the firebox
as an insert. 5BKQFI>QB>KV@>SFQVQLM>KA?LQQLJTFQESBKQPPNJJB>@E5BKQLMBKFKDPQL?B?FOA>KA

Firebox - The Stainless Steel firebox is basically rectangular in shape with a sloping rear back plate to provide
reflective heat and to assist the migration of burner gases to the top of the firebox, exiting at the underside of the top
frame section. The firebox height is 670mm high x 950mm wide at the front frame. Depth from the front of the firebox
to the rear vertical back plate is 340mm. The vertical rear section is 300mm high from the base of the firebox. The
internal surfaces of the firebox have a burnished polished finish that presents a spectacular “hologram” effect when
the burner is in use.
The fascia frame on the sides and top are 50mm in width. The frame is constructed from heavy duty 5mm Stainless
Steel. The bottom frame is 20mm in width and is a strengthening stiffener as well as a finishing detail.
The burner is a standard Jetmaster 850 SFB constructed entirely of Stainless Steel including the burner frame, front
panel and cover plate (but excluding the valve and operating components of the burner). Operation of the burner is
manual ignition and flame control, with a standing pilot. Electronics are not offered on outdoor fires in the interests of
durability and simplicity.

Jetmaster 850 Bedrock Outdoor Flueless Fire Hebel Heat Cell (N.T.S.)
The 75mm Hebel Heat Cell to contain the firebox, is able to be in contact with timber framing on the base sides and
rear of the firebox. The exception being that no timber or combustible materials is located within 600mm of the top
outer face above the firebox.
Build the timber frame out for the Hebel Heat Cell to the following internal clear dimensions (this can be either at
floor level or at an elevated level above floor level) as shown on Fig. 3
W = 1090mm H = 785mm D = 450mm
The following installation sequence should follow:
•Line the interior framing with 75mm thick Hebel panels cut to the below sizes. Secure Hebel Block to timber
framing. Glue panels on abutting faces. $KPROB>IIGLFKQP>OB@LJMIBQBIVPB>IBAM>OQF@RI>OIVTEBOBQFJ?BO
CO>JFKDFPFK@ILPBMOLUFJFQV
Hebel Cell Block sizes are;
Base 1090 x 450 : Rear panel 1090 x 635 : Side panels 2 x 635 x 375 : Top 1090 x 450
• A floor protector (hearth) is not required for a timber deck in front of the fire.
• Slide the Jetmaster 850 BROFF Firebox into place inside the Hebel Heat cell, ensuring it is centralized. Take
note that the thickness of the outer surface material must be taken into consideration and allowed for before
the firebox is secured to the Hebel base and framing.
• Secure the firebox in place with 4 x SS tecscrews or similar into the underlying Hebel base / timber framing, as
earthquake restraints.
• The firebox has a central 15mm dia. gas entry hole drilled into its rear situated 50mm above the base.
•Fit the gas burner, ensure the front legs are screwed to the firebox to secure the burner in place, connect the
gas and randomly place the 20 Bedrocks on the vermiculite bed in the burner tray as required. There are 20
rocks provided with each fire in sets of 5 of varying sizes. Additional rocks may be purchased if required.

• ENSURE NO COMBUSTIBLE MATERIALS ARE LOCATED WITHIN 600mm above the fireplace opening, irrespective
of whether installed into a timber frame out or masonry heat cell.
• A floor protector is not required for any installations above a timber floor.
• All Jetmaster 850 Bedrock Outdoor Gas fires are supplied standard with a SS weather cover that fits over the
front opening of the firebox with two locking handles on the sides. Refer to Fig. 4.

Stainless Steel Weather Cover
The SS weather cover is made to fit around the exposed frame of the firebox 950mm x 650mm in size. Refer to Fig. 4.
If recessed (for a totally exposed outdoor installation), it is recommended that the front of the recess be no more than
100mm with an additional peripheral clearance to the outer edge of the frame to permit the weather screen to be able to
be placed and removed with ease.
Provision should also be made to provide a drip line groove to the underside of the top recess. The minimum
opening size of the recess to take the firebox outer frame would need to be; 960mm wide x 675mm height x 100mm
depth. Should a recess look not be desired, it is recommended that a Hebel mantle be used 50mm above the top
frame protruding a minimum of 100mm out front and a minimum of 100mm to each side. Incorporate a drip line
groove.
