1.
What type of gas can be used?Top
All Empire heaters
operate on Natural or LP (liquefied
petroleum) gas.
2.
Can the unit be converted from LP to
natural gas?
Top
All the vented
units can be converted from LP to
natural, or from natural to LP. Empire
has kits available for the conversion.
3.
What size heater do I need to heat my
room?Top
There are many
variables in determining the correct
amount of heat. You should consult your
local dealer/installer who can,
firsthand, see the space to be heated and
determine a size based on the type of
construction, floor plan and climate.
4.
How big is the unit (width, height,
depth)?Top

5.
Are vent-free heaters safe?
Top
YES – Since
1980, vent-free gas heating appliances
have been equipped with a unique safety
pilot system called an oxygen depletion
sensor, or ODS. The ODS is the proven
technological innovation that
revolutionized the safety of vent-free
gas heating appliances. In 1995, the
Vent-Free Gas Products Alliance of the
Gas Appliance Manufacturer Association
(GAMA) commissioned a study on indoor air
quality as it relates to vent-free gas
heating products in the home. The results
proved that vent-free gas heating
products meet and exceed the most current
and applicable nationally recognized
standards and recommendations for the
indoor air quality.
6.
Do vent-free heaters take all of the
oxygen out of the room?Top
All products which
burn gas and draw combustion air from the
living space "take oxygen" from
that space, (Gas ranges are vent-free
units). The owners manuals on our
products and your local code official
will inform and instruct about the need
for make up combustion air.
Vent-free heaters have an
ODS or Oxygen Depletion Sensor which
automatically shuts off the gas supply in
the rare event that the oxygen level in
the room falls to 18% This is above
unsafe levels as established by ANSI
(American National Standards Institute).
7.
How much moisture is produced by the
vent-free heater?Top
Vent-free units
when used as supplemental heating devices
generally do not add any more water to a
living space than the bathroom shower
does in a normal day. Specifically, for
every 1,000 Btus, the vent-free unit will
create 1 ounce of moisture per hour.
8.
Does the venting come with the DV units?Top
Venting is included
on the following Direct Vent Models:
DV-210, DV-215, DV-25, DV-35MH, DV-55,
DVC-35, DV-20E, DV-40E, DV-55E
Most units have vent extension kits
available.
9.
Which units require electricity? Top
Units that require
electricity to operate are:
High-Efficient
Direct Vent Wall Furnace
Vented Counterflow Wall Furnace
10.
Which units come with blowers?
Top
Most units have an
optional blower available. Blowers are
standard on the following units:
Empire High-Efficient Direct Vent Wall
Furnace
DV-20E, DV-40E, DV-55E
Empire Vented Counterflow Wall Furnace
DVC-35, DV-55
11.
Does the blower increase efficiency?Top
The blowers
designed as an integral part of the unit
generally help a unit achieve a
relatively high efficiency. (DV55 is 77%
efficient AFUE).
Optional or accessory blowers are used to
move the warmed air around only, they do
not increase the units efficiency
12.
Can I use a remote control and a wall
thermostat together?
Top
It would depend on
the type of unit you have. In general,
both are offered as alternative
controllers, they can be combined. Please
consult with your owners manual or your
dealer.
13.
How far can the thermostat be from the
unit?Top
A unit that
requires electricity to operate generally
has a 24-volt thermostat as its
controller. This thermostat can be a long
way from the unit without worrying about
wire size. For example, on 20 gauge or
normal thermostat wire, the thermostat
could be 50, 75, and if need be 100 feet
away from the heating unit.
A
unit that operates off of a millivolt
wall thermostat is generally limited due
to the theater being able to produce
about _ volt or 500 millivolts. 16 gauge
wire is recommended up to about 20 feet
and 14 gauge after that up to about 35
feet maximum (the thin wire and
relatively long wire runs add resistance
to the millivolt system which can keep
the control valve from operating because
of not enough voltage left at the valve.
14.
Do you stock parts for old units?
Top
Empire tries to
keep parts on all units up to 20 years
from last production. They can be
purchased through your local dealer.
15.How
long will these units last (life
expectancy)?
Top
We have records
that with proper maintenance and care,
the units will last 10 – 20 years.
16.Can
you send me an instruction manual for an
old model number?Top
We do have
owner’s manuals available on all
units that have been manufactured by
Empire Comfort Systems
