INSTALLATION INSTRUCTIONS cont.
CAUTIONS
properly sized and fi tted according to the installation codes. Upstream of the supply connection, the fi tter shall provide a manual shut-off valve.
1. All installations must comply with local building safety codes.
2. Installation shall be by a licensed, qualifi ed installer experienced in heating equipment installations.
3. THE WOOD SECTION MUST BE VENTED INTO A CHIMNEY APPROVED FOR SOLID FUEL
USE IN GOOD CONDITION. MOST GAS FURNACES ARE VENTED INTO “B” VENTS, THIS
IS UNACCEPTABLE FOR SOLID FUEL APPLIANCES. THE APEX CBT MUST NOT BE
VENTED INTO ANY TYPE OF CHIMNEY THAT ALSO SERVES ANOTHER APPLIANCE.
4. DO NOT CONNECT THE DUCT WORK SO REVERSE OR PARALLEL FLOW IS POSSIBLE.
5. DO NOT RELOCATE ANY OF THE CONTROLS ON THE ORIGINAL OR ALTERNATE
FURNACE.
6. Ensure that all existing or alternate furnace systems are in good operating condition before installing the add-on. Always maintain required clearances from the existing or alternate furnace.

If the furnace sits on a combustible fl oor, a non-combustible shield must be used underneath the furnace and extending 18 in. out from the charging end and 8 in. on either side of the fuel-loading door. A non-combustible shield is also required underneath the chimney connector and extending at least 2 in. on either side of the chimney connector. (minimum size fl oor protector= 65” x 31.5”)
It is not required to be a heat protective covering.
This furnace must be installed in compliance with all local codes and regulations.

INSTALLATION INSTRUCTIONS cont.
Apex CBT as independent furnace:
When the blower is installed on the left side of the Apex CBT, the bypass handle needs to be moved to the right
side.
Install the blower more to the front of the unit as that is where most of the heat is. When using the VB1000 blower cut an opening 13 1/4” W x 11 13/16” H in the side panel about 9” from the front (Distance A, see fi g. opening that way. Use the pre-punched cutouts if applicable.

Insulation
DO NOT USE INTERCONNECT DUCT ELBOWS THAT HAVE AN INSIDE RADIUS OF LESS THAN
6” (150mm.). THE WARM-AIR SUPPLY OF THE APEX FURNACE SHALL NOT BE CONNECTED
TO THE COLD-AIR RETURN INLET OF THE EXISTING OR ALTERNATE FURNACE. THE
POSSIBILITY EXISTS THAT THE COMPONENTS OF THE EXISTING OR ALTERNATE FURNACE
MAY OVERHEAT, CAUSING THE CENTRAL FURNACE TO OPERATE OTHER THAN INTENDED.
COMBUSTION AIR
Insure adequate combustion air allowing for all other exhausting type appliances in the dwelling (range hoods, dryers, etc). In airtight houses it is recommended to install a fresh air inlet into the basement room where the furnace is located. Recommended intake size is 1.5 sq in
2 per 1000 BTU’s.

INSTALLATION INSTRUCTIONS cont.
MOVE BYPASS HANDLE SYSTEM FROM LEFT TO RIGHT SIDE FURNACE
In some installations it is necessary to move the bypass handle system from the left (default) to the right side of the right makes place for the bypass handle but need to be installed on the left aft er the change-over). Make sure to adjust the handle position and latch so proper seal is achieved on bypass door. Reroute wiring. Fig. 7 shows the correct mounting of the handle latches when moved to right side.

PRESSURE LOSS
Before any changes are made to the existing furnace system you must establish the working parameters of that system. You can then insure that addition of the add-on has not degraded the operation of the original system, and correct air fl ow will be maintained. Change all fi lters in the system to insure maximum free air fl ow. Using an accurate manometer check the static pressure at the end of a typical duct near the exit to the house. Check the static pressure in the plenum above the existing furnace also.
Pressure drop = Static pressure at furnace -(minus) static pressure at duct exit
Record the pressure drop of the original system.
Addition of the add-on furnace will add airfl ow resistance in the system. Aft er installation is complete measure the pressure drop in the same run measured before add-on installation. If the air fl ow has diminished the blower speed should be adjusted to compensate. When using a belted blower the pulley size should be changed or adjusted to speed up the blower. If the pulley size is adjusted measure the blower motor current to insure that it is still within the motor plate specifi cation. It may be necessary to replace the motor with a more powerful motor. If a direct drive blower is used change to a higher motor speed. Do not change the blower size.
