The holiday wrapping paper arrived in the furnace room because it was long and awkward. A camping chair followed because it was only there for a week. By autumn, the room had become a storage cupboard with heating equipment somewhere inside it.
I started by taking the loose things out. Then I looked up the equipment's required clearances and asked about the access needed for service. I had been judging the gap by whether I could squeeze through it.
Leave the required space open

Gas-appliance safety includes keeping the equipment area clear and following its installation and operating instructions. Combustible materials, flammable products and blocked air openings do not belong around a furnace. The required distances depend on the equipment and installation; a number borrowed from another house is not a reliable rule.
I moved paint, aerosols, cardboard and household clutter to appropriate storage elsewhere. I did not add shelves to the furnace enclosure or cover an opening that seemed draughty. An opening can serve a purpose I cannot identify by looking at it.
Make maintenance possible

NRCan's maintenance guidance involves checks that require access to equipment components. The technician should not have to move our belongings to reach a filter cabinet, drain or service panel. I also wanted the route clear if we needed help unexpectedly.
We agreed that nothing would be stored in the marked working area. I kept the marking outside the equipment and away from labels or vents. At the next visit, I asked the technician to confirm the arrangement.
The wrapping paper went into a cupboard upstairs. It falls over occasionally, but that is a storage problem I can solve without compromising the room that heats the house.
