    You need to check local requirements, but...
    In most if not all locations, the door to the room must be sealed, combustion make-up air cannot be drawn from the bedroom.

    "G2406.2 (303.3) Prohibited locations. Appliances shall not
    be located in sleeping rooms, bathrooms, toilet rooms, storage
    closets or surgical rooms, or in a space that opens only into such
    rooms or spaces, except where the installation complies with
    one of the following:


    1. The appliance is a direct-vent appliance installed in
    accordance with the conditions of the listing and the
    manufacturer’s instructions.

    2. Vented room heaters, wall furnaces, vented decorative
    appliances, vented gas fireplaces, vented gas fireplace
    heaters and decorative appliances for installation in
    vented solid fuel-burning fireplaces are installed in
    rooms that meet the required volume criteria of Section
    G2407.5.

    3. A single wall-mounted unvented room heater is installed
    in a bathroom and such unvented room heater is
    equipped as specified in Section G2445.6 and has an
    input rating not greater than 6,000 Btu/h (1.76 kW). The
    bathroom shall meet the required volume criteria of Section
    G2407.5.

    4. A single wall-mounted unvented room heater is installed
    in a bedroom and such unvented room heater is equipped
    as specified in Section G2445.6 and has an input rating
    not greater than 10,000 Btu/h (2.93 kW). The bedroom
    shall meet the required volume criteria of Section
    G2407.5.

    5. The appliance is installed in a room or space that opens
    only into a bedroom or bathroom, and such room or
    space is used for no other purpose and is provided with a
    solid weather-stripped door equipped with an approved
    self-closing device. All combustion air shall be taken
    directly from the outdoors in accordance with Section
    G2407.6.
    "

    "Code Commentary: The intent of this section is to prevent
    fuel-fired appliances from being installed in rooms and spaces
    where the combustion process could pose a threat to the occupants. Potential
    threats include depleted oxygen levels; elevated levels
    of carbon dioxide, nitrous oxides, carbon monoxide,
    and other combustion gases; ignition of combustibles and
    elevated levels of flammable gases.

    In small rooms such as bedrooms and bathrooms, the
    doors are typically closed when the room is occupied,
    which could allow combustion gases to build up to
    life-threatening levels. In bedrooms, sleeping occupants
    would not be alert to or aware of impending danger.

    If an appliance obtains combustion air from a room or
    space, it communicates with the atmosphere in that room
    or space whether or not it is installed in that room or space.
    An appliance might be in a room, closet or alcove and obtain
    combustion air from an adjacent room, so Section
    G2406.2 is worded to address the location of an appliance
    in the rooms listed and in spaces that open only into such
    rooms. In other words, an appliance in a closet accessed
    from a bedroom is no different from an appliance located
    within the bedroom. It is not the intent of this section
    to prevent combustion air from being taken from a
    bedroom, bathroom, etc. as evidenced in Items 2, 3
    and 4. For example, the volume of a bedroom could be
    added to the volume of other rooms for the purpose of
    providing indoor combustion air for an appliance not
    installed in a location prohibited by this section if openings
    are installed to conjoin the space volumes in accordance
    with Section G2407.5.3. If an appliance obtains
    combustion air from a room, the appliance
    combustion chamber would be open to the room and
    the appliance must be considered to be in that room.
    Item 1 recognizes that direct-vent appliances have
    sealed combustion chambers and obtain all combustion
    air directly from the outdoors. The appliance combustion
    chambers do not communicate with the room
    atmosphere.

    Item 2 requires that the room be able to supply the
    necessary combustion air by infiltration as specified in
    Section G2407.5. Note that Item 2 includes both
    vented decorative appliances and vented gas fireplaces
    which are both addressed by ANSI Z21.50 and
    are essentially the same appliance, known by different
    names. Vented gas fireplace heaters (Z21.88) were
    also added to Item 2.

    Items 3 and 4 allow the installation of a single
    wall-mounted unvented room heater in bathrooms and
    bedrooms if the heaters are equipped with oxygen depletion
    safety shutoff systems, are limited in Btu input rating
    and the space is capable of supplying indoor combustion
    air in accordance with Section G2407.5. These exceptions
    specify “wall-mounted” heaters, which are fully enclosed
    and less susceptible to tampering and other conditions that
    might affect the combustion process. Items 3 and 4 would
    not apply to room heaters that stand on the floor or fasten to
    a fireplace hearth or ventless firebox hearth [see Commentary
    Figure G2406.2(1)].

    Item 5 would allow installation of fuel-fired appliances
    within a separate dedicated space that is accessed from
    the rooms and spaces listed in this section. A separated
    space containing the appliance must be open to the outdoors
    in accordance with Section G2407.6, and the access
    door to the space must be solid and weather-stripped to
    prevent communication between atmospheres in the separated
    spaces. The door must also be self-closing and not
    rely on occupants to keep it closed. The enclosure must not
    be used for storage or any other purpose. The intent is to
    isolate the appliance(s) from the rooms listed in this section
    and to obtain all combustion air directly from the outdoors
    [see Commentary Figure G2406.2(2)]. This item can be
    used to avoid relocating an appliance when an existing appliance
    installed in a prohibited location needs to be replaced
    [see Commentary Figure G2406.2(2)]."
