MG1E-Series 80% AFUE Gas Furnaces NAT GAS Orifice Selection
NATURAL GAS ORIFICES: Use the following steps to determine appropriate orifice for installation altitude.
- Consult Local Utility for “LOCAL HEATING VALUE” at installation site. Use “Local Heating Values” chart to determine if this value is considered “LOW” or “HIGH” based on installation altitude.
- Use “Natural Gas – High Heating Value” or “Natural Gas – Low Heating Value” chart to determine appropriate orifice based on furnace model.

DUCT CONNECTOR INSTALLATION DETAILS
- E7-Series, MG1E-Series, MG2R-Series, and M5SB-Series
Step 1: Select duct connector based on distance/depth from finished floor
to supply duct. Duct connector is lowered into hole through insulation ring.
Corresponding hole is cut in supply duct to match duct connector finger/screw
tabs
Step 2: Mounting bracket with tabs is slid underneath and Ncentered side- to-side. Duct connector is then attached and sealed to supply duct using industry-approved methods – see furnace installation manual for more details.
Step 3: Duct connector is then attached to the floor using appropriate
screws, flat-head nails, or staples.
Step 4: Furnace is slid back to against mounting bracket and secured to floor using methods detailed in install manual.
