General Information
1.0 Introduction
Thank You and Congratulations for choosing an Ambiance Gas Fireplace insert!
The UF0500-2 is among the most advanced Direct Vent Insert heaters available today. It is solidly designed using the latest technology
and manufactured to the highest quality. It is our aim to provide you with an appliance that brings many trouble-free years of reliable
service.
Some of the many features of your UF0500-2 are:
• Heater Classication This replace is classied as a heating appliance. Therefore, it uses Direct Vent safety technology
and it is suitable for continuously operated zone heating.
• High E󰀩ciency This replace has one of the highest e󰀩ciencies of any Direct Vent gas insert, ensuring it is less
expensive to operate.
• Adjustable Fan Speed This replace comes complete with an adjustable six speed circulation fan controlled with the
remote.
• Adjustable Flame This replace provides the ability to adjust the ame aesthetics and heat output to suit the owner's
liking and heating needs.
• Adjustable Lighting Use the included remote to choose from six levels of accent lighting or leave the light o󰀨 and allow
the ame to provide a ickering glow.
• Solid Construction This replace is mainly constructed of 16 and 18 gauge galvanized and aluminized coated steel for
long life and durability.
• Optional Accessories Speak with your local Authorized Ambiance Dealer for a full complement of decorative accessories
to suit your home's decor and personal tastes.
• Electronic Control System This replace comes standard with the Dynamic Start Advantage. This new electronic ignition
system is the latest in replace technology. It helps to create a better draft, better ame
appearance, less condensation on the glass, and years of carefree operation. See Section 19.4 for
complete explanation of how the system works.
• Multiple Electronic Pilot
Settings This replace uses a gas control valve that is operated by a Multifunction Remote Control. It can be set up as either an Intermittent Pilot Ignition (IPI) system, or Continuous Pilot on Demand Ignition
(CPI) system (also known as a Pilot on Demand (POD)).
CPI vs IPI:
Continuous Pilot on Demand Ignition (CPI): In this mode the pilot runs continuously even when the main burner is o󰀨. The
Continuous Pilot on Demand Ignition operates on a seven day cycle. If the main burner is not turned on for seven continuous days, the
pilot will turn itself o󰀨. When the main burner is lit again the cycle repeats. The pilot will remain lit for seven days, even after the main
burner is turned o󰀨. If the main burner is lit during a seven day timing cycle, the seven day timer will reset.
Intermittent Pilot Ignition (IPI): A fuel saving mode in which the pilot is only used when the main burner is on.
This appliance is shipped in IPI mode. IPI mode is often the preferred method, however, there are some situations where it may be
preferable to switch the replace into CPI mode. For example, in colder climates the glass door or the front of the replace could
become very cold to the touch. Dynamic Start Advantage will solve most problems experienced by older IPI operated replaces.

9.1 Factory Built Fireplaces
The following information applies to Factory Built (metal) Wood-Burning Fireplace installations:
Trim panels must not seal ventilation openings in the replace. Any parts that are removed must be saved and reinstalled if the insert
is ever removed. If the factory-built replace has no gas access hole(s) provided, an access hole of 1 1/2” (38.1 mm) or less may be
drilled through the lower sides or bottom of the rebox in a proper workmanship-like manner. This access hole must be plugged with
noncombustible insulation after the gas supply line has been installed.
The damper (A) and grate with logset (B) must be removed or fully blocked open.
The smoke shelf (C), internal ba󰀪es (D), screen ( E), masonry lining or refractory (G and I), and metal or glass doors (F) may be
removed.
The replace must be permanently marked to indicate that it has been altered and is no longer suitable for burning any fuel unless the
removed parts are reinstalled (See Figure 9.0.02). Cutting out of any metal parts is prohibited, except the metal oor (J) as specied.
The insulation (H), and any structured rigid frame member must not be removed or altered (side and top of door frame, side and top of
the face of replace, metal sides, etc.).
The metal oor of the rebox may be removed only if the following is strictly adhered to.
The metal oor (J) may be removed to allow additional room for installation of the insert as long as it does not compromise the
structural integrity of the existing replace. If the oor is removed the insert must be placed directly on the metal base of the metal
replace. Under no circumstance can it be placed directly on a combustible material.

Installation
11.0 Gas Connections
Before connecting the appliance to the gas supply line, double check that the appliance you have purchased is designed for the
gas type you are using. The gas type markings are located on the rating plate (See Section 4.0 and Section 6.1) and also on the
appliance’s gas valve.
Adequate clearance for proper installation and checking of the gas connections must be provided. All gas connections must be
checked for gas leaks.
Have your gas supplier or a qualied gas tter run a gas supply line into the solid fuel replace. The line must be properly sized and
tted according to the installation codes. Immediately upstream of the supply connection, the tter shall provide an accessible manual
shut-o󰀨 valve. When connecting the supply line to the gas valve, the installer shall brace the gas valve to ensure that the gas valve is
not moved from its bracket. If the valve is not braced when the supply line is connected, the valve may be moved and cause a “break”
in the main burner supply line. Such damage is not covered by the manufacturer’s warranty.
CAUTION: The appliance and its individual shut-o󰀨 valve must be disconnected from the gas supply piping system during any
pressure-testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). The appliance must be isolated from the gas supply
piping system by closing its individual manual shut-o󰀨 valve during any pressure-testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kPa). Failure to do so will damage the appliance’s gas valve. Such damage is not covered
by the manufacturer’s warranty.
Natural Gas Pressure Settings:
The inlet supply or line pressure must be a minimum of 5.0” W.C. (1.2 kPa) and a maximum of 14.0" W.C. (3.5 kPa). The orice is a
#37 DMS (2.64 mm) drill size.
ELEVATION INPUT RATING
0-4500 ft (0-1372 M) 31,500 BTU/hr (9.2 kW)
4500 ft (1372 M) and above. 31,500 BTU/hr (9.2 kW) less 4% per 1000 ft. (305 M) above sea level.
Please contact your local distributor for the appropriate orice size you require.
Propane Pressure Settings:
The inlet supply or line pressure must be a minimum of 12.0” W.C. (2.98 kPa) and a maximum of 14.0” W.C. (3.5 kPa). The orice is a
#51 DMS (1.73 mm) drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 M) 29,500 BTU/hr (8.65 kW)
4500 ft. (1372 M) and above. 29,500 BTU/hr (8.65 kW) less 4% per 1000 ft. (305 M) above sea level.
Please contact your local distributor for the appropriate orice size you require.
11.1 Clocking Procedure
IMPORTANT: THE INPUT RATING SHOULD ALWAYS BE CHECKED WHEN FIRST FIRING THIS APPLIANCE.
Before you begin, shut o󰀨 all other gas appliances including any standing pilots. Light the replace and wait 15 minutes. Clock the
time to burn 1ft³ of gas on the meter. Check with your gas supplier for the gas BTU content at your elevation. Input is the rate of ow
multiplied by the heating value of the gas (cubic feet/hour x BTU per cubic feet). Note: This assumes a dry gas meter at 1/2 psi. If using
a 2 psi dry gas meter the unit will rate lower as the calculation has to correct for the higher pressure in the meter. If the unit is over-
rated, contact your authorized Ambiance dealer. The following calculation equation gives a rough estimation as it does not correct for
temperature and pressure.
